It is only possible to reduce below zero using Flat Armor Reduction. Since doesn't have anything like that, he can only use the other forms of armor penetration like Flat Armor Penetration which doesn't account for values below zero.

I tested this to make sure nothing changed by using a minion and there was no damage increase using Armor Penetration runes.
