I haven't found any. However, there is a rule governing extensions beyond the Frame Perimeter--Specifically, no more than 14 inches. The Fender is sloped on the top, and the short side is higher than any vertical surface that's been climbable in FIRST history (besides the bars, which have had little or no vertical surface).

Besides, given FIRST history, I would expect that as soon as a "climb on the Fender to defend the goals" strategy goes public, the next team update will specifically disallow it.
