If Norway is held it was the Norwegian Army and its shore batteries that stopped the invasion in an early stage. They probably had support from the allied navies and some allied air support. Allied ground troops won´t arrive sooner than in OTL and would be probably less numerous because the Norwegians already have the situation under control.
Unless the Fall of France is somehow butterflied away, the allied victory in Norway might not last long. The Germans need the iron ore less since they now control the french, belgian and luxembourgian deposits but in case they decide they need it anway or can not tolerate the British at the northern flank. The British would have a hard time. They have one dozen ill-equipped and one dozen ill-equipped, understrenght and not well trained divisions.
The Swedes better announce a full mobilisations because I see a few dozen germany divisions send to Baltic ports. That´s outside the range of both the RAF and the RN, so the Germans would have secure SLOCs for an invasion of Sweden. Given the superior quality and quantity of Wehrmacht ground forces I doubt Sweden and Norway would survive a full scale assault.
Very, very, unlikely.
Depending on how the attack fails, you could be looking at most of their warships and a lot of transports, ie the stuff that would be needed to carry an invasion, being sunk.
Kind of hard to invade when you have no means whatsoever of getting your troops there to begin with.
