How do you remove a clog without losing all freon from the thin copper tube on the low pressure side of a split AC that is frozen for 10 inches then a couple of fittings and it is warm from there on?

Answer:

Answer

There should be a pump down valve at the condenser. One for the suction and one for the liquid side. Simply front seat the valve on the liquid line and wait for the unit to pump down, then front seat the suction side and cut the pipe and replace.

You may want to install a liquid line dryer before you evacuate the system and recharge the unit.
