If you have a compatible motherboard then this will work. But I highly doubt it will be compatible.
the problem with replacing the core 2 duo with the newer i5 is the size and pin difference, the core 2 duo is simply smaller than the i5, you would have to buy a new mother board, which in most cases it would be cheaper to just buy a new laptop with the i5 or i7 in it.

The Intel Core Duo.
You can replace an Intel Core Duo Processor by first removing the heatsink and/or fan from the processor and removing the old thermal paste. Apply thermal paste to the new Intel Core Duo Processor and reseat the heatsink and/or fan.

´Dual core' just means that there are 2 separate cores in the CPU. Intel has made dual core pentuim 4, core duo and core 2 duo CPUs. ´Core 2 Duo´ is just one type of dual core CPU that Intel has made.
There is no difference between dual core and core 2 duo. Intel just name its recent family of dual core processors as "core 2 duo". Both (core 2 duo and dual core) works in same fashion.
