I don't think it was so much a war as it was a falling out between the Romulans and the Klingons at some point after the Khitomer Conference (and perhaps the Tomed Incident too), IMO. The two sides have probably never been friendly with one another and if their territories butted up against one another, they may have been frequently engaged in occasional border clashes. Both Khitomer and Narendra III may have been in territory that the Romulans considered theirs and took steps to remove what they considered uninvited guests (the Klingon colonists on both worlds).
I can't imagine why the Klingons wouldn't declare war on the Romulan Empire after the Khitomer attack, the Klingons would have considered that a dishonorable attack and 4000 dead Klingon colonists would more then enough reason to justify a war with the Romulans. The Klingons went to war with the Federation for far less then that, the Klingons actually would have reason to go to war with Romulans, but they didn't, that seems very out of character for them.
This would be like after the Pearl Harbor attack, the US didn't declare war on Japan, that wouldn't make sense.
Not every nation declares full-out war upon another. Some conflicts are short, small-scale affairs in areas of disputed territory. I don't think even the Klingons declare war without first weighing the pros and cons.
