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?

Thinset is cementatious, mastic is organic...it's the stuff you paste
down vinyl with.

I have no idea what orange Shuluter sheet is but I rather doubt it.
Unless it is cementatious so thinset will bond. But your best
alternative is to rip up everything including the sheet goods, put down
cement board properly and re-tile. Hell, you only have 30 sq.ft.
