SURE!  It's even the right way to do it. In a typical battery portable 
operation, there's no good reason to use a common mode choke or any form 
of "balun."

The only situation in which a good ferrite choke could be useful is when 
the rig is somehow earth-referenced, as it could be when used at home 
running on mains power, or with the chassis tied to earth ground.  In 
that situation, the feedline could pick up noise and couple it to the 
antenna, and the choke prevents that.
