No chance. Current laws were not devised with this sort of thing in mind, and I doubt that that will change (what percentage of legislators do you think know you can installed a different OS on a PC from the one that came with or would care if they knew).
I also very much doubt they wan to open this can of worms. Almost every technology business is trying for customer lock-in of one sort or another (Google subtly, Apple blatantly, Amazon very cleverly) and they would all oppose it. A good many non-tech businesses would see benefits in locking down technology more, most importantly the media.
Governments these days are business friendly, and real competition is unfriendly!
