I think so long the actual logo isn't present, it should be okay? There's a lot of knock-off logos for stuff like coca-cola and Uniqlo stores in a lot of premium comics I've seen! It's also sort of funny to see something like BUCCI in place of the actual logo, but it wouldn't take away from the fact it's your universe's version of the luxury label since most people recognise them as is.
Otherwise to be safe, you could always slightly alter the design (changing colour scheme, slight alteration of a hemline, sleeves..), but ultimately I think the actual logo should have a knock-off design instead to avoid any legal trouble!
