From my experience, if a motor is 240V capable it will be written/stamped on the plate as being capable of dual voltage. However if it's wound for 415V in delta, it will most likely be marked as 415V only.
However, until you dismantle it and check how the external wiring links to the coil wires, you can only make a guess.

There are a couple options to avoid a motor swap. If you can live with reduced torque at higher speeds, you can run the motor via an inverter on 240V. HowTo: 240V Supply to a 400V AC Motor - Application Detail explains it well.

Or you can get inverters that will step up 240 to 415V - DIGITAL 240 TO 415 INVERTERS | Drives Direct Inverters LTD
