No, they can't, at least not in bitcoin-qt: when the user pokes the SEND
button, the transaction is broadcast on the network, and then the merchant
is also told with the Payment/PaymentACK round-trip.
Allowing merchants to cancel (e.g. having a PaymentNACK) makes
implementation harder, and brings up nasty issues if we want to allow
CoinJoin or CoinJoin-like transactions as payments to merchants.
Bitcoin-Qt ALREADY allows you to pay several PaymentRequests with one
transaction; handling the case where one merchant gives you a PaymentACK
and another gives you (or wants to give you) a PaymentNACK is a nightmare.
