The cage you linked is only 22x24 unfortunately.
And yes they might say 24x24 minimum but I think most people will agree that minimum cage sizes are just big enough to not constitute neglect. I mean I've seen minimum cage sizes of 12x18 for budgies and other small birds and that is like making them live in a shoebox. Personally I think if your bird is going to be inside of its cage for more than a few hours you should aim for as big a cage as possible (at least enough space for plenty of toys and space to move around). Is there anyway you could fit a cage into a different (larger) space?
I agree about the min. size but someone gave me a link to a cage that was 38x38 that is bigger than I want.
I don't plan on going with the min. size just not the size for a big macaw.
I had a full size macaw with the really big cage.
Also I am home all day so the bird will be out most of the day not in the cage.
