Is the ground lead length limited? I noticed that the Chez Radio only references FCC Rules on this subject.

Same as the U.S. rules in theory. In practice, IC is a lot more lenient.

Is the ground lead length limited? I noticed that the Chez Radio only references FCC Rules on this subject. Yes and no! We have 2 sets of rules that apply here. There's RSS-210 and BETS-1. RSS-210 gives you a choice but it also depends which issue was in force at the time(year) the transmitter was certified. RSS-210 has amendments from time to time that supersede past amendments. It says, 100mW into the final amp NO modulation with the same ground and antenna rule as the USA OR 250uV/M@ 30 meters with NO antenna or ground rule. You can pick one or the other to comply with. BETS-1 says only 250uV/M@ 30 meters with no mention of an antenna or ground length or power. You have two categories regulating the 520-1705 KHZ band and 88.1-107.9 MHZ FM band. So an advantage here if you want to do AM and don't have the facilities to do the set up outdoors with grounds/radials etc. or don't want to worry about the ground length rule. You can put the transmitter anywhere you want.

We should try for BETS-1 AM here. No need to worry about FM here.
