I stained an outdoor swing set with Cabots semi-transparent redwood stain. The color is not what we thought it would be, it is way too red. The test board I tried didn't really show us how red the entire swing set would be. Does anyone know of a chemical treatment that I could apply that would lighten the color? Maybe something with an accelerated aging effect? We would like it to be less red.

Short of using a chemical paint stripper, I don't know of an easy way to lighten the color. You could try applying a lighter color stain or apply a solid stain of the color you want. Go to a real paint store that carries Cabot and see what they suggest. And, test it on an inconspicuous spot before committing to the whole item.
It's always easier the make an item darker but difficult to make it lighter.

++1 for Howie. You can try oxalic acid—bar keepers friend—on an inconspicuous place and see what happens. If that works you can buy oxalic acid from paint stores or Amazon—if it doesn't work you have a great cleaner for enamel and metal around the house.

So would a paint stripper take the stain out? Or mostly out? I had thought that since the stain was down in the wood that nothing would take it out. I was thinking that a separate chemical treatment of some kind might just darken the stained wood. I am open to suggestions.

I'd try oxalic acid first. Less expense and work. If that doesn't work then try a methylene chloride paint stripper. Wipe it off with paper towels or the cloths used for detailing cars. Discard them frequently.
If that doesn't work I'd consider painting it.

Try a raw umber stain over the top of the red, this will both darken and kill much of the red look.

The colorant in the Cabot stain is a pigment. Pigment stains remain mostly on the surface with little or no penetration. Using a chemical paint stripper containing methylene chloride will remove almost all of the varnish and stain. At that point you may find that the residual color is minimal and your new semi-transparent stain will cover it. If some colorant remains, try using chlorine bleach. A fresh bottle of Clorox mixed 1 part Clorox to 4-5 parts distilled water will lighten the remaining color. (Oxalic acid is used to remove black water marks and other mineral stains--not useful here).
As a final option as I previously mentioned is to you an opaque deck stain which will cover the remaining prior color.

Thanks for the advice. Using paint stripper looks like the best option. I'm glad to know I have an option at all.
