Do both base64 (from coreutils) and uuencode -m and uudecode (from sharutils) implement base64 encoding and decoding? Can they be used exchangeably?

Try man uuencode, which will demonstrate that they're not synonymous.

I can't figure out if they are exchangeable as far as base64 encoding/decoding is concerned.

There are (at least) two different mappings for base64. You'd have to read the source-code to be certain that they're the same.

Except for the header and tail that uuencode adds to its output, yes:

$ uuencode -m - <<<"Hello World! test"

begin-base64 644 -

$ base64 <<<"Hello World! test"

SGVsbG8gV29ybGQhIHRlc3QK

But uuencode is specified by posix, base64 no.
