The death note necessarily need the person's real name, it cannot be a nickname or surname and also must have the person's face in your mind.

in other words, if light wanted to kill lelouch, light necessarily need his full name would also see his face, and even if light saw the face of lelouch, for me and for many, would be very difficult that lelouch says his name and more without raising any suspicion.

If you want to know the rules of the death note here of leave two links that you read them.
