Absolutely, a ten year old computer today is still capable of doing pretty much everything that most people use computers for. It's not like the old days when every few years a new tier of computer would come out that made older devices no longer capable of doing what people wanted.
I was still running a Q6600 (a 2.4 gHz quad core from 2007) until a few years ago. It ran most things acceptably for its entire life - it wasn't until around the time of PS4 Pro/Xbox Whatever ports that it could no longer keep up, and even that was largely due to the other components I was restricted to on such an old motherboard.
That thing was also a tank. The CPU cooler was stock and the thermal paste had degraded and separated to the point it idled at 65c, but I never had a single hardware fault in nearly fifteen years of running it. I kind of miss it.
It depends on how good it was to start with. I have a machine from 2006 that is usable for daily tasks. I also have a netbook from 2009 that can barely do anything.
