Older Asus fold had many issues with Linux. In most cases, you can get headless mode working but forget about GUI. A better solution would be trying out System76, HPDevOne or Dell XPS dev edition for Linux desktop.
The Purism Librem 14 isn't half bad either. Currently using it. Love the build quality of the case, matte screen and kill switches. Quality of the built-in speakers is not that great. Keyboard is acceptable. The trackpad is nice and big.
