Yes, you can use the COPY_SRC_OVERVIEWS creation option of the GTiff driver : 
http://gdal.org/frmt_gtiff.html. However, be aware that if you use any option 
of gdal_translate that needs an intermediate VRT (basically almost any option 
except the driver creation options), the source overviews will not be seen by 
the GTiff driver.
