Batteries are a replaceable component, apple doesn't make it easy but it's not particularly harder than any other device. It's not soldered in and doesn't touch the top-case. Now: if the battery expanded and caused internal damage (bending the top case and damaging the keyboard) then what you said makes sense, but that's a pretty glaring omission if so.
