Should be able to. It appears to be 400V star connected so if you reconfigure it as a delta motor it would need 240V. Would pull a bit extra current if fully loaded but that should be OK.
All six winding ends seem to be taken out to the terminal box (looks like the top two rows in the photo) so you would just remove the shorting bar from the top three and then reconnect something like this

That is assuming each winding is connected to terminals that are in line. You would need to do a continuity check as they sometime do the step internally so that the delta links are just vertical (ie one winding will internally connect to say the top right terminal and the bottom middle)
Great. I'll do a video after work of a continuity check of all connections. Should I pull off the short bars so all terminals are isolated first? the motor is off an old wood working machine, maybe a thicknesser.Even easier than that, most 3-phase dual voltage motors are set up with the winding ends already staggered, so three short, straight links and you have delta... With the links off, there will be open circuit from one to the other "vertically" and as Pete says, from one of each vertical pair to the opposite of the next pair.
The pair at the bottom of the pic may be for a thermal switch, to disconnect (via a contactor) if the motor overheats, or even a magnetically operated brake (hard to tell without a pic of the other end of the motor).
