   Probably - depending upon which ones that you remove and the current   
   that they are now running on and the maximum current that they can run.   
      
   Easier would be to keep all the LED's and replace one of the resistors   
   with a higher value one.  That would reduce the current in the LED's and   
   their brightness.  Put a pot in place of one of the resistors and   
   experiment.
