But that supports the point OP made above. Each generation of Lenovo laptop changes out lots of parts (presumably based on changing prices and supply contracts). Apple laptop hardware tends to be stable over time.

I'm confused where you got that idea. T2 chips changed a lot. The most recent Intel MBPs have a different wifi with a known-broken firmware for Linux. The sound handling has also changed and hasn't been reverse engineered yet since 2019. And that's before we even get to changing the entire architecture to M1. How is that less changes than lenovo?
