Yes, although the higher the impedance, the more the balun's own strays
will come into play. (Note also that at QRP levels, a large balun such
as the BL1 should have negligible heating loss over a very wide
impedance range.)
I'd suggest experimenting ahead of time with the tuner, balun, and
typical antennas.
