Probably, yeah. Though not necessarily because of THIS or any other rumors about to be referenced - it's just kind of an easy call. If and when Carol Danvers eventually turns up in the Marvel Cinematic Universe, it'll be the least surprising "surprise" for fans since Captain America turning up in the present day.
Marvel, on the comics side, has had a decade-long obsession (coupled with very successful execution) with turning Danvers, aka "Ms. Marvel," into one of it's A-list heroes ever since someone figured out that she could easily be their answer to Wonder Woman (re: highly-marketed Strong Female Hero) sans all that problematic "Love-Powered Animated Clay-Doll From The Island of Immortal Lesbian Warriors" baggage.
She's been a big part of most recent Avengers iterations, features in most crossovers and was most-recently promoted to "Captain Marvel" (short version: She started out as the surprisingly more-popular distaff-counterpart to the original MALE Captain Marvel. Long version HERE and then HERE) Also, the Avengers DO kind of have a diversity problem and, let's face it, action-heroine, Joss Whedon movie, etc. So yeah... when/if she turns up in the movies the only thing less shocking will be the chorus of dissapointed sighs when/if Marvel decides her costume needs to be another teardown/rebuild job a'la Hawkeye.
That said, I'm not necessarily inclined to fully dismiss this particular rumor because it makes sense given a lot of what's already known about the now-unfolding buildup to "Avengers 2."
Here's the thing: Ms. Marvel's setup is a touch on the complicated side (given how Marvel Films has operated up to this point, one has to assume keeping her backstory and "arc" close to the basic source is a priority.) There've been some retcons as to how "important" she is pre-powers, but the general idea is always that she starts out as a military and/or government agent who gets powers similar to Captain Marvel after being caught in an explosion during one of his battles.
Going by the way Marvel Films has operated up to this point, it's a safe bet that she'd probably get introduced "normal" in one of the next pre-"Avengers 2" movies... Or maybe more than one: it'd make perfect sense to make her a S.H.I.E.L.D. agent, and they are in need of a new movie-to-movie connector character i.e. Coulson. If "Agent Carol Danvers" were to turn up for an introduction in one movie, then get zapped full of cosmic space-powers in a subsequent movie (like, oh... "Guardians of The Galaxy," the cosmic space-power focused movie already positioned as the direct lead-in to "Avengers 2," perhaps?) she'd be all primed and ready to turn up in "Avengers 2" as the "newcomer team-dynamic shakeup character."
Here's the other thing: The story that started the rumor said they were looking specifically at British actresses, one of whom is Emily Blunt (originally cast as Black Widow before she had to bail and Johansson got the job, so theres history with the producers) who was also mentioned as being in the running for another Marvel role - the as-yet unnamed female lead in "Captain America 2." Most people have been assuming that role would be Sharon Carter, daughter (granddaughter?) of Peggy from the first movie, but it could just as easily be Carol Danvers.
