They have other chips that can run Z80 code (eZ80, Z180), but none that are drop-in compatible as far as I know. If you're looking at putting one of these in place of a Z80 you'd probably need to either redesign the surrounding computer or essentially treat it as a giant "peripheral" on a new firmware/kernel retooled for the new processor (like some "accelerator" products have done historically).
