If the whole board is the CPU, we typically don't call it a CPU. (The C is for Central.) There's very few left, but there's still hardware out there, running code, that could be called CPU-less.
I do take your point that it's down to pendantic wording, at that point. Something very like a CPU, that most of us are going to just call a CPU, is going to be present.
Yeah. There's certainly an argument to be made that whatever is left is not really the Linux Kernel anymore, after modifying it enough to run CPU-free. But I suppose it's still more fair to call it Linux, than not to, at that point.
Microcontrollers aren't "the whole board", following that definition, an SoC wouldn't have a CPU either.
MCs require support components. Clocks, power converters, level shifters, modem, etc. You'll hardly wire a barrel plug and a servo directly to a DIP (though that would be pretty cool).
