Denmark is considered to be adjacent to Sweden, with a canal/strait connecting between it and Skaggerak/Baltic. Analogous to Constantiople, which is adjacent to mainland turkey and Bulgaria, with a strait connecting the Black Sea to the Aegean.
If you look at the map posted, where the dot is, is still part of Denmark, as is the water shown in between the pieces of Denmark.
So, yes, you could consider it moving along the coast. If you had an army in Denmark, it could march to Sweden.
Edit: Page 5 here goes into detail on the tricky parts of the map.
