You jest, but remember that younger adults these days (i.e. the future market) are quite happily moving from phone/tablet/tv-thing/laptop/car and mode-switching amongst the various interfaces.
A generation of *perfectly fine* corporate laptops rendered unsupported and sold to the refurbishers may well end up being deployed with a suitable linux and sold on.
Alternatively, Microsoft may be complaining that businesses are failing to update in a few years (because the businesses don't want to send perfectly usable devices to refurb/landfil)
