First question about the upgrade in the title, would it be a significant upgrade and would I see a noticeable increase in general performance?
Also, can I actually upgrade my old laptop to the new processor? I checked and it's on the same socket type, what else should I look for?

There is no soldered version of the cpu. The real issue is bios compatibility, which you can't check, and if it can handle the extra heat which you can figure with your current temps. It's the same 35w tdp but ht and the higher clocks is going to be slightly hotter. Most laptop cpu upgrades are just a shot in the dark. Also with the age, I'd wonder if it's even worth spending money on. You'd probably be better off with getting a ssd. That could be re-used. If it has less than 4gb ram, then that could be an issue as well. What do you use the pc for and what performance issues are you having?

Provided it isn't soldered to the motherboard, should there be no problems with me simply swapping the old one out for the new i7?

Cooling is another big issue. The pentium is a low end low power model. Unless the laptop also came with a i7 in other variants I wouldn't upgrade to it.

Physically, it should work, like k114 mention Bios and heat issues are the bigger concerns.

If Bios is not compatible, the pc won't boot (black screen) at worse, while at best, the cpu will work but might be limited (less speeds, less core ect.)
You might want to contact the laptop manufacturer to see if it is compatible.

The other problem is that the i7 will use more power thus produce more heat. If the laptop cannot cool itself you are looking into throttling (slow down), computer shut down ect.

The i7-640M can run at a higher frequency and is hyperthreaded so in theory could provide more than 50% processing power, but as said there are problems.

BIOS?
Cooling?

Even if it all worked the CPU may end up throttling down a lot due to insufficient cooling.

*The ONLY way to know is to find someone else with the EXACT laptop that did the same thing.

OTHER:
If the laptop is sluggish maybe swap the HDD for an SSD (clone) and possibly reinstall Windows.
