I voted probably. Why?
Bethesda has the ultimate say in what is and is not canon- however, it's been shown in the past that Bethesda doesn't make decisions in a vacuum; if anything they released is, without a doubt, elicts a negative player reaction, they'll make an attempt to correct it in the future. Thus, if Mothership Zeta proves to be widely unpopular with the fans, then Bethesda at a later date will make the effort to not mention aliens again, putting it in the Limbo of "is it canon?" Of course, this is if they decide not to come out and say it's not canon.
As for the TARDIS/Federation of Planets; tell me, can you point to a single peice of pop culture that has something called the Alien Blaster? Or something that looks exactly like it? Probably not; unlike the TARDIS/Federation of Planets, there's no real singe peice of pop culture that uses it, instead it's spread across seperate works of sci-fi dating to the pre-moon landing era when Outer Space was the big unknown (trust me, we now know far more about Space than we do the Earth's Oceans... More people have walked on the moon than dove to the deepest depths of the ocean.)
