Which is... exactly about the positioning of words, if you can or cannot lead with a certain word.
Nevertheless, you are always allowed to use a trademark in a factual sense, as in "Windows can now run Android apps on the Desktop" (modulo some TM or R sign, I guess). That they gave this feature a marketing name at all is a marketing decision - it doesn't have to have a noun. Or it could use a cryptic, non-trademarked internal name like WOW64 does. Or you could go for "'nix subsystem" or "penguin subsystem" or "APK subsystem".
This is why I am convinced even if there we no legal reasons, they would call it "Windows Subsystem for Linux / Android". I think they want to psychologically distance the product from the Windows NT idea that you can have multiple types of applications on equal footing, instead of just "Apps" (see how they are muddling the names of Modern/WinUI/UWP/App SDK/... Apps). But in the end, no one can know and it is just interesting kremlinology...
