No, parts are a complementary business (bcs of how the business/market is set up, life cycle of the laptops, the price of the parts is arbitrary, not marketed, etc - it doesn't exists without the core business).

What makes financial sense doesn't really have to make any economical sense unfortunately.

But I would want to live in such a place where it would.

Having said that, Lenovo sure seems to be making some sensible headlines recently.
