Whether or not your computer will support it is not the issue. Tiger legally can not be upgraded to Snow Leopard without purchasing the full boxed copy which is $125.00. Only Leopard can be upgraded for $29.
While you are calculating the cost of this upgrade seriously consider adding additional memory. The absolute minimum required is 1 GB it will run much more smoothly with additional memory.
Your machine can support SL ok, but I didn't realise as cschag has pointed out there are legal issues with doing it this way (thanks cschag), also as Slydude has pointed out a RAM upgrade will really help with running SL too.
