Why not? Fury has gone rogue on several occasions in the comics, so there's plenty of precedent. He disobeyed a direct order from his superiors on the Council in Avengers, and Avengers features deleted scenes that have the Council pretty much grilling Maria Hill to build up a case against Fury; so there's definitely a plot point still hanging out there that the Council clearly wants to fire him.
In any event, I doubt Fury would *permanently* lose his position; he'll probably be back to Director at the end of the movie as everything gets back to normal.
