I'm pretty sure it is, since Kojima himself said in Ground Zeroes that its story was still canon, despite that being the perfect opportunity to ensure people got that Portable Ops was canon (remember, they already had the storyline for MGSV down when Ground Zeroes was made, and only needed to tweak the gameplay engine and record dialogue before release, so Kojima would definitely have known about whether it still fit into canon or not.).
