You can, but it rarely gives an improvement (except if the first TDNN model was trained with the "e2e" scripts). You have to be careful with options, e.g. --alignment-subsampling-factor, to some of the scripts (if you get this wrong it will crash). You can look for examples with the "e2e" scripts for how this is done.
