I'm afraid I have to agree with Aaron if you RAW the Trading rule. It simply states: "The Survivor can simultaneously exchange any number of cards with only one Survivor who is on the same Zone."There is no restriction on what type of card may be exchanged, so therefore a Wounded card may be exchanged with another Survivor. Note that the Wounded card isn't being discarded so trading the card doesn't conflict with the no discarding rule.
Now I must qualify all this by saying I would never play it this way as I don't believe it is the intent of the rule to allow the trading of Wounded cards.
I believe that this would be solved simply by an errata along the lines of "Insert 'Equipment' between 'any' and 'cards'"
I guess a FAQ is in order....
