No, the Canon PowerShot V10 is not compatible with the Sony Tough G 128GB CFexpress Type B.
Canon PowerShot V10 has a microSD-only card slot (no CFexpress support of any type). Its own compatible-cards manual page confirms only microSD/microSDHC/microSDXC card compatibility -- CFexpress Type B uses a physically different, much larger connector and cannot be inserted into a microSD slot.
