Yes, but you should really be on the boardwalk along the lake, not behind the BWV on the canal to DHS. Also, you will only be able to see the higher level fireworks from outside the park. You need to be in EPCOT around the World Showcase to see any of the show that happens on the Globe.
IMO, if you aren't going into EPCOT, the best view would be from the bridge over the canal that goes between the lake and EPCOT's International Gateway.
