When we talk about Linux, we're usually talking about GNU/Linux. Android/Linux is a very different beast, and it's not pedantry to draw a distinction between them. The capabilities of GNU/Linux are closer to BSD than Android/Linux.
Except they're really not different. Just because Android runs a distinct userspace and windowing system doesn't make its Linux kernel any less Linux. You can easily install a Busybox userspace on a rooted Android device, and on top of that you can start building an entire GNU/Linux userspace, complete with package managers and X server. Install a VNC viewer in Android, and you can even connect to your local X server and have a fullscreen X session.
By that logic BSD is also exactly the same thing as Linux.
