The answer is "only if you're willing to destroy information" for all MIME types except 'text/plain; charset=us-ascii'. How do you reach that conclusion for text/html? The first two RFCs establish the requirement that mail shall be transmitted as plain ASCII text.[1] The rest provide various conventions for how to serialize quite arbitrary objects, from non-ASCII text to video clips to binary blobs, as plain ASCII text. HTML is made of plain ASCII text.
