Theoretically yes. This is an issue that has been considered before, though admittedly not with regards to fucking Greenland. Turkiye and Greece have long been enemies as well as members of NATO, and it’s been considered that the invocation of Article 5 by the aggressed-upon party against the aggressing party in case of a serious war would, theoretically, be binding on the other members of NATO.
In practice, NATO is a gentleman’s agreement with no means of enforcement. Everything comes down to political will - NATO is just an organizational structure to facilitate a response. It cannot replace the will (or lack thereof) of national governments.
