I have literally loaded Debian Woody (circa 2002) onto a modern 64 bit Linux kernel from over 20 years later, and it just works.

As for "more stuff", I'm not sure what you are referring to but I suspect it's difficult to compare. Linux's networking, hardware support, debugging and introspection facilities, files systems (off the top of my head) have always been way ahead of what Windows offers. I suspect that until DRM, Windows GUI / GPU was a long way been ahead of Linux particularly after they virtualised the GPU (in Vista?). But perhaps Linux has caught up now by slicing the cake differently.
