TPMs, due to their role, work across orgs and interface more with leadership so they do seem to get a lot more visibility/exposure than normal ICs and do seem to get promoted into leadership positions more easily. My wife is less technical and is looking for a career change and last year I literally suggested this path for her.
(you can argue separately that this isn't as important which I might agree with on a case by case basis in that I've seen really strong leaders who are less technical who make up for in various ways but it's not the common case).
