So my game, Cyberspace Warp (this: https://itch.io/jam/gbjam-11/rate/2280015 ) was made in TIC80, and I was wondering, could I add the original .tic file in the description so that mobile users can play it or smth.

(Note, I said original file, not an updated one)

I included a Game Boy rom in my game's download page, dont see a reason for other systems not being allowed.

you can’t upload it now, but after the rating period ends you should be able to upload it. i think itch lets you upload any file type. if not, you could upload it to dropbox, google drive, or something and link to it on the page.
