Certainly--but someone buying an Android device thinking "it runs Linux" would probably be disappointed. Linux is there, but from the perspective of the average user it might as well be a custom kernel or even the Windows kernel, because without "surgery" and tweaking, you'll only be running applications built for the Android stack. I've chopped out the Java layers of Android and run my own software on there, but it took some work to get my application running with the Bionic libc and the Android-specific devices.
