Welcome to the forum!
Yes, that CPU will work. However, it has a higher TDP than the dual core models so cooling it may be an issue. You will need to ensure you correctly clean the old thermal compound and replace it with a good quality one like Artic Silver 5, Artic Cooling MX-4 or Noctua NT-H1 to name a few...
Also make sure to clean the fan's blades using compressed air. When doing this block the fan with your finger to prevent it from spinning to avoid damage.

You mean more powerful than the i7-2630QM? The L420 supports Sandy Bridge CPU's, so in theory you could try any of these:
However the cooling will still remain an issue, and I guess the more powerful the CPU the hotter it will run...
Edit: What applications are you planning to run? I can think of few software where quad CPU's would make a notable difference. For normal office/web operations the performance jump won't be that huge.

hi thank you for your reply you are very nice.
I use FL studio and Ableton Live for making music so I need maxium cpu power.
but I do not want my laptop to get too hot.

I would love to upgrade to a
so would this upgrade be safe?

Well, the procedure is safe, but I personally would be worried about the heat. I took a look at a L420 heatsink and it doesn't look very thick.
My recommendation would be to very careful when applying the thermal paste:
Good luck and keep us posted!
