You can shoot .40S&W out of a 10x25mm semi-auto pistol.
But, it is not safe to do so.
After the 1986 FBI Miami shootout (8 FBI agents vs 2 bad guys = 2 bad guys KIA, 2 FBI KIA, 5 FBI WIA of which 2 medically retired due to the injuries. 1 bad guy did all the damage to the FBI and had been shot 3 times with 9mm prior to doing so), the FBI determined that the 9x19mm was an inadequate service round and looked for a replacement. After testing, they determined the 10x25mm was what they wanted.
S&W and Winchester created the .40S&W, after realizing that the ballistics of the underloaded 10mm "light" rounds that the FBI were using could be replicated in a smaller package.
In the early-1990s, the FBI issued the 10x25mm S&W Model 1976, but due to compliants about the size/weight of the handgun from field agents, it was replaced by an interm pistol in the mid-1990s, the 9x19mm SIG P-226/P-228 (agents had a choice). In the early-2000s, the SIGs were replaced by the .40S&W Glock 22/23 (agents have a choice).
