At the level of the user-mode instruction set, they are compatible with MIPS-I/R3000 - indeed, the basic pipeline looks like it was taken directly from the R3000. But the system coprocessor was radically modified and simplified and in particular there is no TLB/MMU. Standard Linux therefore won't fly on it, though some variant of uClinux might.
