No. That machine only has a 32-bit kernel.
In terminal type,
If the output shows RELEASE_i386 you have a 32-bit kernel and cannot boot in 64-bit mode.

Thanks, but so now does that mean that although I'm running an application like Logic Pro in 64 bit mode it wont actually run in 64 bit mode, henceforth utilizing more RAM than 4 GB?

I believe that 64-bit Logic Pro will run in 64-bit mode even though you have a 32-bit kernel. Just because the kernel boots and runs in 32-bit mode doesn't change the physical architecture of your processor. So the 64-bit limits apply to a 64-bit running application, not 32-bit limits. Of course the application itself may impose limits of its own which are possibly smaller.
