Yes. G25 says, in essence: Thou Shalt NOT Intentionally Detach Parts From Thy Robot.

This rule has existed since 1998, and is also known as "Beatty Rule #1". Back in 1997, you didn't have to have a tether if you left something behind, so 71 (or whatever their number was back then) would make it impossible to score in a certain area once they'd scored by leaving a structure behind. (Beatty Rule #2? No metal on carpet, but that's another story.)
