References to Norway may frame Shakespeare's Hamlet, but the conflict between Norway and Denmark is not in any way central to the play. The references provide background information in Act I (the king of Norway's death at the hands of King Hamlet, the threat of invasion, etc.), and catharthis and cleansing in Act V (the evil is destroyed and Fortinbras will stabilize the political situation in Denmark). Fortinbras also serves as a foil to Hamlet, of course. But, again, this political and military conflict is not central to the play.
Thus, you should probably think in terms of what this conflict contributes to the play as a whole, rather than think of what occurs in the royal bedroom contributing to this conflict.
That said, the one event that occurs in the royal bedroom that does affect the conflict between Denmark and Norway might be Hamlet's killing of Polonius. This moves Claudius to send Hamlet to England and order Hamlet's execution. The conflict between Claudius and Hamlet is in the "feeling out" stage before Hamlet kills Polonius. In other words, Claudius is not sure Hamlet is out to get him until Hamlet kills Polonius. The killing gives Claudius the excuse he needs to get rid of Hamlet, and the opportunity to have him executed away from Danish soil. The killing of Polonius might also lesson the high opinion the Danish people have of Hamlet.
In turn, Hamlet discovers the assassination plot and overtly returns to avenge his father. Thus, the king is preoccupied. He is worried about Hamlet, not Fortinbras. Claudius appears politically astute in the early acts of the play, but later he never considers that Fortinbras will disobey his orders and invade Denmark anyway. By the time Fortinbras invades, Denmark offers little resistance.
Other than that, the unseen sex between Claudius and Gertrude and the appearance of the Ghost probably do not directly affect the conflict between Denmark and Norway. Hamlet also berates his mother in her royal bedroom, but this has nothing to do with Norway.
If you must connect the royal bedroom with Norway, Polonius's death is probably your best bet.
