It is highly probable. Dick is a master detective who, just like Batman, knows everyone even if they don't know he does. (Example: Artemis Crock's family background before she revealed it and the character itself who is known as a master detective with skills rivaling Batman himself). Superman...well....has x-ray vision LOL. But he also knows Batman's secret identify and can therefore figure out his identity.
