Isn't there a requirement on the airplane itself for a 135 operation?

Yes. However, a flight school operating a Part 135 operation will have some
or all of their fleet certified for the Part 135 operation. Presumably, if
the CFI was using the Part 135 operation as a legal safety net, he'd make
sure they took one of the Part 135 planes.
