the disc version can play all discs but the 10 mentioned as well as all digital games but the 10 mentioned. the digital only can't play discs but can play digital games. Really straightforward. All Ps4 games but 10 listed (none of which are likely to upset you) are able to be played on PS5 day one. 

Why those ten specifically? They don't seem to have anything in common.

As it's pretty much impossible to fully test the whole game catalogue for new bugs due to BC, I'd wager the 10 listed games simply produce fatal errors during game boot. Others might show problems aswell, but I guess Sony atleast did a bit more indepth testing for the most popular titles to make sure it's good enough in atleast one of the BC modes (PS4 / PS4pro / PS5).
