The question isn't "can war exist without nation-states"; the question is whether hostilities between non-nation-states should be called war or not. The answer doesn't change the fact that group A is trying to kill group B, and you can reasonably expect group B to try to prevent that.
Now possibly it has legal ramifications because the word "war" has been used sloppily in treaties, etc, but none of that changes the reality of people killing and/or defending. Besides, there isn't a clear definition of "nation-state", so even if we can't redefine "war" we'll just re-define "nation-state" to mean whatever we need it to mean in order to fit the offensive / defensive actions we think are appropriate into whichever subset of the treaties we'd like to continue to pretend matter.
