It would make sense to design this way, to conserve battery since a weaker signal would be needed with the mouse within close proximity to the USB receiver.
No.
To vary the power in a way that would conserve battery use you would need telemetry back to the mouse - meaning a transmitter and reciever at both the mouse and computer.
It's easier and cheaper to just run a fixed power output at the mouse.
