you can self book a reward ticket using the Amex voucher online without speaking to anyone as well as phoning in, but worth saying that although this is not done currently, they could easily identify if an Amex card is one of the BA ones via the BIN number (first 6 digits). Many payments systems use this to limit which card types they accept and or process. My own card, which kept the same BIN through over 20 years of upgrade and downgrades, still used to be identified as a BA premium even when I had temporarily downgraded to BLUE.
EG. Some of the earlier BA Amex BINs were:
BAPP Amex 374614
BA Amex 379108
