Yes you can do that, but the memory won't run in DDR mode.
You need matching memory in matching sizes and specs to run the memory in DDR mode.
You would probably get better performance with 3 GB of memory, vice 2 x 1 GB of memory running in DDR mode, because more memory is better.
But yes, your PC will work just fine with 3 GB of memory.
Best would be 2 x 2 GB of memory.
