When it comes to applications, Android is very different from any Linux distro. Android apps rely almost entirely on Google made additions on top. Something like waydroid could bridge the gap but I don't have first hand experience how good it is.

Linux is just a kernel which means that someone needs to develop the userspace. There are plenty of distributions of Android, but it will be pretty different if you swap out the user space with something else entirely.
