In brief: Maybe, maybe not

Diphenhydramine (benedryl) is and antihistamine.
That means it blocks a pathway involving a chemical called histamine, which is released especially with allergy issues. Thus, benedryl with decrease congestion, but only congestion caused by histamine. Cold/respiratory infection congestion is not caused this way and thus wont be blocked by this medication well. There are other options...
