It is very difficult to upgrade components in a laptop. The CPU may be upgradable, but it is not very easy.
Because of the small size of a laptop the graphics card is usually welded on to the motherboard so almost impossible to upgrade.
I also have to say your CPU, a Celeron, is one of the slowest CPUs you can get, and your laptop may not even be able to take in Intel Core 2 Duo (you cant fit an AMD CPU as your laptop is desigend to take in Intel not an AMD).
You graphics are also basic "on board" graphics so again at the very low end.
I am no expert on gaming, but to play this game you are going to have to get another laptop, and not just a "basic" one but one with a semi decent graphics card it it.
Most cheap laptops have basic "on board" graphics that are only suitable for "office" type work and watching basic videos like YouTube and cant cope with anything more demanding, and most games are very graphics demanding.
