the infinite tsukoyomi would have to affect black clover as well, and I doubt that those two continents wouldn't notice one another due to the outrageously gigantic wars they're fighting. I guess it would be possible, but there's no exact motive or reason to believe that they could be. Keep in mind that I'm only caught up with the black clover anime, but the grimoires are a universal system in black clover, so if they were on the same planet naruto characters should have them. Naruto and Black clover also very clearly play in different times, where Black Clover is more focused on medival-type times, We already have cameras, microphones, TV's, etc. in the narutoverse.
But on the other side, this concept would be extremely interesting considering Yami's origin story. TLDR; I don't see a particular reason for this to be plausible, but it's still a fun thought
you might have to swap some things around but i've seen people make the continents outside of the ninja world be anything from hyrule from zelda to d.c. comics America. as long as you put in the effort i've found that most fanfic readers are fine with the mixing and matching of different universes
