I currently have an i5-2410m in my laptop with a 35W TDP and am upgrading to a i7-2630qm with a 45W TDP. How much will this affect the battery life of my computer?

you will have to take the laptop apart to find out if the CPU can be replaced.
Also understand that some laptops use custom cooling designed for the the CPU TDP and upgrading it may cause the system to overheat.
PS many laptops also have custom bios where they specifically avoid supporting certain CPU's to prevent people from upgrading.
it is also hard to find mobile CPU's because they are not sold retail.
I recommend not doing it even if the CPU uses a socket connector unless there is a really good return policy on the CPU. There is just too much that can go wrong with this since nothing is really standardized.

On an unload scenario I think the time will be the same. In a fully load scenario, is very hard to tell, check what is the current consumption of your machine, if is 100W the battery will last at least 10% less, 4 hrs -> 3,6 hrs (but this is a very raw calculation)
