A lot of "non Android Linux distributions" like sailfish os actually use a lot of Android infrastructure to keep working.

Drivers doesn't just mean the kernel. It's the user space binary blobs and services that need to talk to the kernel to enable the hardware.

Other than that there's waydroid, alien dalvik etc.. that run another Android instance in a container.

The thing is a lot of Android applications use safety net/other methods to make sure they only run on. "Approved"/stock hardware.
