It's all irrelevant because operating systems in general are NOT named after their prominent components. It does often happen that the kernel and the OS have the same name, but that is not because the OS is named after the kernel but rather the other way around--that is, the creators of the OS name the OS, and then the kernel is known as the X-kernel, where X is the name of the OS.

If I choose to take the Linux kernel, GNU utilities, and assorted other free software and put them together to form a complete OS, I can call it whatever I want, and BY DEFINITION that is the correct name for my operating system, since I'm the one who put it together.
