That would be nice but what other alternatives are there? It's either Chrome, Edge, Firefox, Safari, or clones of these browsers.

Probably or probably not. The only way to find out is to try. I've installed RetroPie on a number of old laptops; the oldest one being a 2002 Toshiba laptop. I got to play GBA games just fine with it.

You can try turning it into a retro gaming station by installing RetroPie. Some have got it working on as little as a Pi Zero. Of course, that laptop won't be able to run the more demanding emulators.

If you need S3-compliant storage for testing and development, you can use an S3 mock server. I've tried the following for use in web development and CI environments, they are lightweight and configurable:

• Adobe S3Mock
• s3ninja

There is also Localstack. I found this one to be a bit more complex than the ones above and ended up not sticking with it.
