Not "legal", perhaps, but the Men in Black have been actively discouraged from doing so. One example was the combination of Star Munchkin and The Good, The Bad and the Munchkin, which was often run under a title suggestive of a popular single-season SF TV series from 2002-2003 - which could be taken to imply that SJGames held a game licence for that series, which is not only not true, but could impair negotiations in that direction.
