In fairness: the Windows NT OS/2 subsystem doesn't have the OS/2 kernel, the "NT Virtual DOS Machine" doesn't have a vanilla DOS kernel, and there's no Unix kernel in Windows Services for Unix. So they're all named after the thing that isn't really there, and that the Windows NT kernel substitutes for.
Furthermore, only some of the (free) software bundled up as Ubuntu is "GNU". Being copylefted doesn't by itself make something part of the GNU Project.
The annoying thing was the Microsoft video where twice Rich Turner of Microsoft stopped Russ Alexander to clarify what was happening and gave incorrect clarifications of how things were "running on Linux ... on Windows". They patently are not "running on Linux".
Microsoft has been quite happy to say over all these years that OS/2 1.x programs were "running on Windows" and DOS programs were "running on Windows" and Win16 programs were "running on Windows" and even Win32 programs were "running on Windows", M. Turner. This is just plain "Linux programs running on Windows". There is no need to make it confusing when it actually isn't. (-:
