Why does a Cortex-M processor have a process stack?

Does it not have an MMU and cannot implement processes, but only threads?

You are basically correct. Some implementations have MPU, but there are none with MMU. https://developer.arm.com/documentation/107565/0101/Memory-protection/Memory-Protection-Unit

I think 'process' is a more general term than 'thread', though I do not know if that is the reason.
