Yes

From gdal_translate man page:

       -b band:
           Select an input band band for output. Bands are numbered from 1. 
Multiple -b switches may be used to select a set of input bands to write to 
the output file, or
           to reorder bands. Starting with GDAL 1.8.0, band can also be set to 
'mask,1' (or just 'mask') to mean the mask band of the first band of the input 
dataset.
