Can I use the Bugaboo wheeled board on the frog? I saw it on the Cam and thought it looked like I could attach it in a similar way. But I don't want to invest if it won't work.

Officially, then, the sibling wheeled board accessory is not recommended and supported for these (and your) Bugaboo models. However, I do believe that with pretty much the same rear bars, the old Bugaboo Cameleon and Frog SHOULD be compatible with the wheeled board WITH ADAPTER for the Bugaboo Cameleon (2007 model).
The question also is that, as older models, these strollers could get seriously strained to damaged by being used with the extra weight of the board and the child on it on the rear axle that is more than 15 years old!
My own advice would be not to use it there... but if you absolutely need it, I would definitely try it with the Cameleon+ (2007 model) adapter. A good way is also to get an older board used with the older Cam before second-hand - it will be cheaper and you can even go and try it out in real life if the seller is close enough.
If not wanting to take risks while still absolutely certain about the buggy board, I have one more suggestion here. Try a Bumprider or a Lascal board that will work FOR SURE while, if your stroller gets damaged or you will swap it for a lighter or a more compact one, you can still use such a universal sibling board on a completely different model.
