Some users tried to install on PC my LigaPro (2nd portuguese league) Option File, which I made for PS4. The major problem are some images I think, I had an user that had to remove the stadium and sponsor images in order to install, and another one had to completely remove the images (all kits, logos, etc.) and install them manually because the game refused to import them. Otherwise, it's fine, all the players, team names, etc are there.
So, I believe you can export a team on PS4 and import it on PC, but you might have to import images manually if it gives an error while importing.
