No, there's no such code in Qt and it's not likely we'll ever have it.

Second, you can't clean the environment. At the very least you need the 
DISPLAY and XAUTHORITY variables, possibly all of the XDG_* ones too.

You're far more likely to be able to remove the variables you don't want / 
need from the application's own environment using unsetenv(3).
