Norway and Denmark don’t have a land border. Thus including alliances in general the Anglo-Portuguese one dates back to 1373, with only 60 years interruption when Portugal was in dynastic union with Spain which in modern terms could be called an occupation.
…and this isn’t just a technicality with both nations being big on seafaring you can consider the water between them a highway, French cannons nonwithstanding.
I’m not quite sure if you’re disregarding the fact that Norway and Denmark haven’t had a war for hundreds of years because they don’t share a land border? In any case i can point out that there were plenty of Norwegian-Danish hostilities before the union time. With both Norway and Denmark being big on seafaring, the waters between Norway and Denmark have historically been seen much more as a highway (as you say about the Anglo-Portuguese waters) than anything else.
The distance is shorter though, so I would rather compare the Norwegian-Danish border to the Anglo-French border, and the lack of a land border there hasn’t really prevented any wars.

Norway occupied parts of Greenland for a while, 1931-1933, I’d call that an act of aggression against Denmark and thus a war even if it was ultimately resolved peacefully and the claim didn’t concern the Danish mainlands.
