Yes, you can use different UART and Run 
 check console ls -l /dev/ttyO*
Result 
crw--w---- 1 root tty     248, 0 Jan  1  2000 /dev/ttyO0
crw-rw---- 1 root dialout 248, 1 Nov 10 13:23 /dev/ttyO1
crw-rw---- 1 root dialout 248, 4 Nov 10 14:37 /dev/ttyO4
 than which want to open UART port
root@beaglebone:~# minicom -D /dev/ttyO4 -b 9600 for example
