No, they are different. Idle reverse cancels the residual thrust that still exists at forward idle, and leads to lower brake temperatures.
HOWEVER, as with all things, you get what you pay for. Our QRH used to only have tables for full reverse and no reverse, until we wanted to encourage idle-reverse landings.
A fat cheque to Mr Boeing and the next revision included an idle reverse table.
In the absence of such a table, using no-reverse would be the conservative option.
