Can a 4 gb RAM MBP that runs High Sierra be updated?

First of all:
MacBook Pro (13-inch, Early 2011)
Processor: 2,3 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Graphics: Intel HD Graphics 3000 384 MB

It has a SSD, so the computer still holds and is pretty fast. Unfortunately, most apps require a slightly newer version and even Chrome doesn't update anymore.
I've read a lost of posts here but everyone has more memory than my computer, so I have the doubt: can I update the computer safely using OpenCore? Anything newer than High Sierra would be good.
