Well by that token Linux can’t claim to be an OS either, since as your own comment mentions it only performs one function of an OS. It’s important that it can talk to hardware but it’s not an OS if it can’t do anything else.
That’s debatable, Linux (the kernel) does much more than communicate with hardware - it manages memory allocations, handles processes etc. GNU is a set of tools. While some tools are needed for the OS to even make sense (without tools it just sits there and does nothing), you could write a simple program used as the init process and nothing else than the program and Linux is needed. Which leads me to believe that the kernel is the OS.
