Can the BBC Master co-processor execute a program in the I/O processor's memory?

Whilst researching the 65C102's memory layout, it occurred to me that, since the I/O processor's memory is mapped to 0xFFFFxxxx, it might be possible to store code there and execute it by setting the co-processor's instruction pointer to a value in that range.

Does this work?

On which co-processors does this work?

What are the side-effects?
