Nope: the physics of the situation is that, with the handle horizontal, the tip will never become completely vertical, the full 90 degrees, no matter how much weight you put on it. It will get close, but will never get completely there. However with a different set up you can easily get 90, just not by doing it like that. Yet that is how most anglers think it is measured.
A bit theoretical I know, as TC's are always very approximate anyway.I view the TC as the minimum weight required to put a 90 degree bend in a rod, regardless of circumstances. Of course the rod can be bent at 90 with the force being much greater than that, the curvature being further down the rod.

"Compression" is an interesting term to apply to a rod too.
