From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I can't speak for these specific laptops, but unlike x86, ARM generally doesn't have a way for an OS to discover the available hardware, and most ARM platforms historically didn't do anything to help. There is a standard for UEFI on ARM where the UEFI is supposed to tell the OS about the hardware, but as far as I know this is only a thing on ARM servers and these laptops might not support it.
Without any way of probing for hardware or getting the information from UEFI, Linux has to somehow be compiled with all the info about the hardware built-in. And the build will be model-specific (there's a way to pass a file describing the hardware to Linux from the bootloader which enables a single kernel to be used on multiple models and have just a small part of the bootloader be model-specific, but somebody still needs to make that file and the manufacturers clearly don't intend to do that).
Yep, an OS would need to be monolithic for a given device.
Something the computer world decided was a Bad Thing in about 1978.
Are we really going back to the dark ages?
