Interesting. According to https://us.battle.net/support/en/article/65159 the game should support Windows 7, so I guess I'd tentatively say there's a fixable bug here. It may be hard to determine and fix, though; my guess is it's validating some version-specific behaviour in its anticheat engine.
IIRC it worked for me with Win 7 as well, but if it is not the case (or maybe not the case now after some game updates), I am not sure we should treat that as a bug, not sure if that worth the effort debugging. There are a lot of things which may concern, e. g., DRM, which have differences between Win7 and later, and currently we are trying to follow Win10 behaviour without probably any example of simulating earlier Windows based on reported version. We are leaving Win7 test failures as broken and, I guess, are about to drop even marking that 'broken' soon.
So if the game works on Win10 prefix and fails on Win7 I guess this bug should be closed, and maybe it is about time to create Win10 prefixes by default?
