Linux isn't an operating system really, it's a kernel. Putting it under computer operating systems doesn't make much sense, because Android itself is a Linux. There's hundreds of Linuxes out there, since the defining component of a Linux is that it's a system that runs on a Linux kernel. And Linuxes, OS X, iOS, and Windows are all Unix-like systems.
