Lenovo engineers good machine, so upgrading the CPU a bit (you already have a decent CPU) won't buy much in terms of performance.

The machine has hard drives.  You will benefit much more by replacing with SSD drives.

PROBABLY.

That looks like a socket 1155 "Sandy Bridge" system so in theory, most CPUs for that socket should work, but there can be BIOS issues and other unforseen issues when you attempt to upgrade a pre-built computer like those from Dell, HP, Lenovo, and others.  You can try it, but be prepared in case it doesn't.

I disagree about it being a decent cpu. It was a low end cpu when it was released
CPU Mark      2293 (G620) vs 8426 (i7-2600K) https://www.cpubenchmark.net/compare/Intel-Pentium-G620-vs-Intel-i7-2600K/1107vs868

In a machine of this age hard disk is probably a big bottleneck

It uses a h61 chipset which encompasses almost all Sandy Bridge CPU's

i also recommend an SSD - it's the best investment you can make, and see a very nice improvement of speed.
also - if the money permits, upgrading to 16 GB Ram helps also

1155 socket is quite old BUT...because nowdays there are lot of people with burned out motherboards holding high end I7s (1155) that just can't get them to work it would be a good idea to sell the whole system and invest a little more money to get a newer system.
Personally i had a system 115 (a cheap MSI mobo +G2030) ..i sold them together...NO way to break the package...along with memory and i got a newer system 1151 with g4560 with just  a little more money with full warranty .

Any given machine was engineered for good performance at the time. Old machines do not upgrade well by replacing the CPU. That has been my experience.   So I agree with the above.  Replace it with something newer that is faster and SSD drive.
