Someone had managed to run Linux on ESP32 in 2021 [0][1]. But that's more of a proof-of-concept rather than a usable thing. Not much information besides that so far I think.

Update:

From the post [0]: someone also managed to run Ubuntu 9.04 on the board in 2020 [2].

Is that also emulating a small arm core, like the guy who got linux booting on an avr chip?

It's emulating a RISCV machine. IIRC there is an extensa port of Linux.
