Or, another way to look at it.

 >>> Could I use the transmit and receive on a single UART independently?

You always use then independently! :-)

The PIC or the USART has no way to tell if both signals actualy
go to a single system on the other side or not. There are
no "connections" between them (apart from sharing some hardware
such as the baud rate generator).
