If doing this, it would be good, after a quarantine period, to put them in a tank that's new to both of them so that one isn't being introduced to another's territory. I know, though, that it's not always possible to do this. The tank should be big enough for both of them, and there should be places for them to go to for privacy/to retreat if any posturing occurs. You'd really want them to be of comparable size, as well. Smaller/weaker ones are more easily bullied by larger ones and would find it more difficult to compete for food.
Putting two turtles together is really a gamble. You'd want to increase the chances of success by providing the best habitat possible and still be prepared to separate them if it doesn't work (and it might work, you just don't know). Can your friend do this?
