IN a pinch, MAYBE. There are a couple of issues:

1-The cartridge is supposed to headspace on the shoulder of the brass case. The 10mm case is much longer than the 40. The shoulder of the 40 will not come even close to the headspace point of the barrel.

2- The 10mm brass is much stronger and thicker around the web area. Also, most 10mm guns do not have a supported chamber. The 40 is much safer with a chamber which provides full support to the case head, mandatory with 10mm loads.

I would highly reccommend against the practice, ever.
