Yes, but there are better tools, specifically MIME-aware tools. Or even perl.
A grep for lines that are 76 characters long and contain no spaces or
punctuation would match the actual encoded attachments, but grabbing the MIME
boundaries is trickier.
^[+a-z\/0-9]{76}$
This will match all the lines in the attachment except the last one.

That way madness lies. Either get a MIME aware tool that will strip the MIME
attachments from the mbox file, or simply strip the encoded lines and don't
worry about the boundary lines (or at least deal with those in a second step).
your attachment will look something like this:
--Apple-Mail-2-649664677
Content-Disposition: inline;
filename*=iso-8859-1''GMT%%A0Receipt.pdf
Content-Type: application/pdf;
name="=?iso-8859-1?Q?GMT=A0Receipt.pdf?="
Content-Transfer-Encoding: base64

BUT, that --Apple-Mail line will appear multiple times in the email (In one
message with a single attachment, "--Apple-Mail-" appeared 8 times), so you
cannot just willy-nilly delete everything up to one of those line.
