The usual replaceable parts are there in the Thinkpad P1 (SSD, RAM) but replacing the speakers, touch pad, screen or webcam is a much more involved process. I also haven't dared look at the keyboard replacement process. I also don't think you stand any chance of replacing the USB ports without a soldering iron once they start showing signs of wear and tear.
I think Thinkpads are actually quite fine for user serviceability, although I do find it was much easier to open my old HP Probook than it was to open my Lenovo P1 gen 3. Lenovo had me dig for a whole bunch of screws and tabs to pull off the bottom panel where HP let me access all the important parts with just one screw and a slide-off panel.
