Yes. It's the same town. Though you have to be careful with names like Waltz from Boda since there are many. The emphasis may appear to be on the second beat, but it isn't. Almost all Swedish polskas have main emphasis on the first beat and minor emphasis on the third, but that first beat may not even be played, so it gets very difficult for an unattuned listener to grasp what's going on. The lengths of the beat and the bow strokes are what varies, so with a non-bowed instrument, one has to adjust as best one can. In bodapolska, the emphasis is still on the first beat, but since it is shortened, it can sound like the second is getting emphasized. It's all much clearer if there is a bass player, but if you ever watch a Swedish musician, look at their feet. The tapping will tell the whole story.
Boda is a town in Dalarna (the so called folkloric region of Sweden). A bodapolska is a particular couple dance from that town and the surrounding region. It is characterized by a short first beat and a sweeping second beat where the woman is sort of suspended briefly in the air.
There are lots of examples on YouTube. Here's a nice one with a strong rhythm, and where you can see the women's movement quite clearly: http://youtu.be/Cx1qx288lZI
Ah. Same town as the namesake of Waltz from Boda?
So one difference is that in a bodapolska, the emphasis is on the second beat, in a hambo on the first. Right?
