No it doesn't. In Marvel, everything, with the exception of spinoffs like Marvel Zombies, is officially tied together in one, large universe. Ghost Rider knows Spider-Man. Captain America knows the X-Men. Mr. Sinister knows of Galactus, and so on.
In Alien and Predator, the franchises are separate. Always have been, since day one. The only linkage is from AvP, in the sense that the two creatures are in the same movie together, nothing more. The links the films wanted to establish with homages and such are not only shaky, but do not make sense.
