There is support for the kernel, so yes, you could now run Arch, Debian, OpenWRT, or DD-WRT much more easily.
Android utilizes old libraries that are not compatible with new kernels (that's at least my understanding of the matter), so you would need to patch it to run a newer kernel, and that could only get you so far.
The newest kernel version that anyone had managed to boot Android with is the latest 4.4.x LTS release.
I wonder if someone could backport the necessary changes from 4.9 to the latest 4.4.x release though, that would already be something.
