Unless someone is suggesting that the Animus also has access to Senu's genetic memories through one of his descendants, I think it's safe to say that this is an actual ability that Bayek had.  

This is actually an excellent point.

In any case, I have never doubted that the intended explanation is that Bayek can literally share the vision of Senu. This is a common element in fantasy settings where characters have a symbiotic relationship with an animal companion. I highly doubt Bayek can actually possess Senu though. More telling is that he actually does say "Be my eyes Senu" even if there's varying degrees of how literal he means by that.
