Read Explanation:
This sentence is an example of the Second Conditional.
It describes an imaginary or unreal situation in the present.
The structure is: If + simple past, would + V1 (base form of the verb).
Here, knew is the simple past form, and would tell is the correct conditional structure.
The speaker does not know his name now, so they cannot tell the listener.
Structure:
If + Subject + V2, Subject + would + V1.
Example: If I had enough money, I would buy a car.
