Not likely that the tiles will crack but the grout will. Why? Because
the tiles are moving? Why? Because the tiles aren't well bedded and
thinset won't stick to the lino/vinyl. You should have bedded them with
mastic instead of thinset. Either that or put down - and mechanically
fastened - cement board on top of the lino/vinyl.

Rip up what you did and do it right.

What's the difference between mastic and thinset? Also, if I install
the orange Shuluter sheet on the other half of the bathroom, would it
help to eliminate the problem? Thanks.
