Yes. Any turing complete processor can perfectly emulate any other turing complete processor, whether it is x86, arm, or riscv. Mainline Linux can then run on this emulated processor without modification.
I respectfully disagree. The turning machine is not doing any set-up before the emulated CPU begins execution, and all of the actual BIOS is done by the emulated CPU.
The mainline part is key.

Damn that’s gonna be slow.
But I guess speed was not a criterion.
It’s technically correct, the best kind of correct.
I guess it’s the difference of can today vs could if this emulator existed…
“boot” is the next important part. Have you tried reading it in full?
Emulated processors can do the same things as physical processors, including booting from disk.
Boot = Bootstrap
If you’ve loaded up a virtual CPU first that’s not a boot of mainline Linux on the CPU.
