BIGTiff would generally get "this is not a TIFF file" because the header has changed.

Besides, if a user tries to open a BigTIFF file with a regular TIFF tool, they will need to get a BigTIFF tool no matter what the file extension is.

The real question here is what error message is presented?

Obviously it will never be the best message: "This is a BigTIFF file, please upgrade to a version which supports BigTIFF".

I would hope that the design of BigTIFF means that the messages are not simply "Cannot open. File is corrupt", but rather something like "file uses an unsupported compression algorithm".
