Is remote wipe of a Mac content possible?

The person does have the ability to remotely erase it via Find My Mac.

If you or somebody else can remove the HD from the laptop and mount it (not boot from it) in an external case or a HD Dock, the data might be accessible unless the disk has been encrypted.

If you have another Macintosh handy, it is possible to use target disk mode. Reboot the MacBook Pro with the 'T' key held down; this will make the computer act as an external hard disk drive, which you can plug into another Mac with a Firewire or Thunderbolt cable. Disassembly is unnecessary.

Copy off any files you require, to a USB key, or burn to a CD or DVD, then erase them (or secure-erase) as may be appropriate. I don't know how this will interact with 'locking' software.
