Can I use the RS232 shield with an "arduino due" if I connect the correct pins with jumpers, instead of use it as a shield? there are something to check?

Since the operating voltage is 3.3V, I am afraid it doesn't support a directly connection. It will damage the board.
There is another way, you can add 1K resisters between the board and shield tx and rx. Plug the shield on a bread board, and connect it to the board with the cable wire. That will be a good idea.
