is this laptop enough to be a minecraft server for me and some kids from school i invite on?

i recently was watching emkay, and when whicher narator it was mentioned turning a laptop with a broken screen into a server, i remembered that 1. ive been wanting to host a minecraft server, and 2, that i had an old laptop that was gifted to me and my brother over 5 years ago(it was decently used and old then). i went and looked up tech by matt's video which ive watched before, but his old pc he used had newer parts than what this old thing has, so is what i have enough?

its has:

an intel pentium b960

4 gb ddr3 ram

a 500 gb hhd

and a working screen

is this enough, should i try getting 8 gb of ram?
