No, in this case (MOD09GA data) you cannot, because the subdatasets have 
different resolutions / raster sizes, and datatypes. Imho there is no 
other way than to subset each subdataset separately. Things might seem a 
bit more logical when you consider the main hdf file as a container, 
like a directory or an archive. You also cannot subset a directory, but 
you'll need to subset each raster file in it by itself.

Best,
Vincent.

Just FYI, I've had the same issue with HDF4 files that contain subdatasets
that are all the same spatial resolution, extent, and data type (multi-band
Landsat).
