I'm just going to put in my two cents here.
It's been a while since I've played the games, but I know this for certain: The DF and AQW maps are NOT connected to each other. The placement of Doomwood, Swordhaven, and Battleon show that the maps are completely different.
On the other hand, stretching the DF map down will allow you to see the same structure from Doomwood down to Battleon and Swordhaven in both BO and DF. Swordhaven is west of Battleon, like it's supposed to be, is southwest of Doomwood, like it's supposed be, etc.
This being said, the bottom of DF's map is cut off while the top and left of BO's map is cut off.
What we can assume here is that DF's map mostly represents the North of that continent, BO's map mostly represents the Southeast of that continent, and the Southwest of the continent is unknown.
While AQW definitely has the West of the continent showing the Sandsea, Volcano, etc, the fact that AQW's locations are placed extremely differently from DF's and BO's shows that the AQW map cannot be trusted.
Please note that the MQ and AQW maps are canonically stated to be different from DF's and BO's since MQ is The Universe V1, DF and BO are Alternate Timelines of The Universe V2, and AQW is part of The Universe V3.
So while DF and BO are on different timelines, they share a nearly identical map due to being part of the same version of the universe, while AQW and MQ have their own versions.
I hope this helps and clears up any confusion. :)
