I know for some old ThinkPads (edit: The IBM branded T60 from 2006) you can get a custom motherboard that works with modern CPUs, but the price for the mobo alone is more than a Framework laptop
If not, I'm not sure I believe you know what you are talking about - its nice lenovo (in past) has been so rugged, repairable, but using reverse engineered parts is a very different thing to a set of components that can be extended.
Put it like this - can you put a lenovo part on a framework laptop? No? Why?
Until you can, Framework is in a whole different category....

The prices of the parts are very reasonable, and each part is labeled with a QR code that can be scanned to access repair instructions.
I do like what Framework is doing, and my next laptop will likely be from them.
I can confirm HP isn't too shabby. Very easy to take apart, and they even put out maintenance and service manuals, at least for their Pro/Elite Desk/Book lines. They show how to disassemble them, the possible part-numbers (for example the different available keyboards with or without backlight).
I've never had to actually source any parts so don't know how easy it is, especially once they get old.
But, in general, I would personally not recommend the laptops. They're cheap junk with ridiculously bad screens.
The desktops are quite OK, though.
If it's successful one would expect availability to increase.
The Framework uses standard parts for wifi, storage, and display. The "proprietary" bits are the mainboard, the battery, and the keyboard/mouse assembly (in the case of the Framework, mainly because of the custom connector).
This is precisely the same situation as with Lenovo, save that the Framework is far more modular and thus easy to repair.
I'm not sure why you think there's any difference.
