It's not a simple question to answer. As you change the length of the coax, 
the SWR doesn't change, but the impedance does. What the tuner can tune 
depends not just on SWR, but on the actual impedance you are trying to tune.

I have a 120 foot dipole fed with 37 feet of ladder line, a 4:1 balun, and 
then 40 feet of RG-8 into the shack. My Icom 746 tunes it just fine on all 
bands 160 through 10. So does my MFJ tuner.
