I understand the idea, yes. But:
1. Most of the time, it doesn't work. Let's face it, at least 95% of the people looking to buy a laptop don't understand this issue. A good amount of people doesn't care about spying either, because they think they have anything to hide, or because the US government is doing it so it must be good, or because the US government doing it makes it impossible to avoid anyway, or for a myriad other reasons. I think Lenovo would have to be in a very weak state for this to do them under.
2. If it worked, it wouldn't be a good thing anyway. The laptop business is a very expensive to enter and competitive one. If people ran a company out of business every time it displeased them enough, despite trying to rectify their mistake, nobody would want to enter the market. Who would want to risk their money in such a way? So the market would eventually stabilize with 2 or 3 remaining companies which are too big to bankrupt, or who people won't boycott because there's too much inertia and not enough alternatives.
If the market settled for instance on Dell and Apple, boycotting one would require rebuilding your entire infrastructure and way of doing things. This won't happen, so if such a situation is reached they can basically do whatever they want.
If we want a consumer friendly environment we need plenty of competition, and this means that bankrupting a company should be the absolute last resort.
