If anyone here has experience with the Icom AH-4 antenna tuner, I

a simple question. Is there any reason I can not extend the control
line beyond the 10 meter length that Icom supplies with a new tuner?

You can extend it, I have done so. If you extend it to ridiculous lengths,
or with thin wire, you can expect to mess up the ATU due to voltage drop in
the ground and +12 wires.
