In brief: Probably not
This is likely a slowly resolving hematoma, which is a blood collection under the skin, basically a significant bruise.
Generally in children this old there will not be health consequences, but if the lump calcifies and hardens, it can be present for months or longer. Typically a cosmetic issue more than anything.

In brief: No, don't worry
A lot of times bruises get calcified (calcium deposits) and it forms a knot.
It usually takes 6-9 months to resolve completely.

In brief: Head injury
No. If he has not had any symptoms for 2 months, the lump is probably just a resolving hematoma or bruise which will be reabsorbed slowly.
