No, and the whole issue of compressed vs = uncompressed is a red herring. If Alice gives = Bob 1MsHWS1BnwMc3tLE8G35UXsS58fKipzB7a, she is saying to Bob =E2=80=9C= I will accept payment to the scriptPubKey [DUP HASH160 = PUSHDATA(20)[e4e517ee07984a4000cd7b00cbcb545911c541c4] EQUALVERIFY = CHECKSIG]=E2=80=9D.

Payment to any other scriptPubKey may not be recognized by = Alice.
