As far as I understand, the thermal limit at 80C and TDP limit at 15W on Linux is what Lenovo actually intended, and the limits on Windows are broken.

At least according to this Ubuntu maintainer: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763144...

That seems like only half of the story. Earlier in that thread, there's this quote from lenovo: " Due to "DPTF" function will act on Windows system by BIOS/Driver support, the system will turn to cool mode when keep high temperature several minutes. But Linux system didn't have driver support DPTF function, it only have TDP limit on platform. So user should have different between Windows and Linux system as normal behavior."

So lenovo is doing something conservative because DPTF isn't officially supported on linux. There seems to be a DPTF repo here: https://github.com/intel/dptf
