The short answer to this is yes but only if one narcissist is overt and the other narcissist is covert. This narcissistic style of relationship is the recipe for insanity due to being at constant love and war. One foot of the narcissist is inlove and the other foot of the narcissist is in a psychosis. The family facade often created via two narcissists in a relationship, maintains itself solely by a delusional way of existing. This is very confusing for a child growing up with two insane narcissists because yes, both narcissists know they are at war while inlove with each other.
