11-speed chain for 1x10 setup?

You could try, but I'd be skeptical of it working. How is the chain going to rub in the bottom gear? Or do you mean the next-to-bottom gear? If it's that dialing out the b tension can be helpful.

I'm not familiar with 10- and 11-speed chains, but if the spacing between the plates of the two types of chain are the same then you could try your idea. But that would mean the 11-speed chain has thinner plates, which doesn't make sense to me. If the 11-speed is narrower because the spacing is less, then it won't fit on the teeth of your cogs and chainring.
Short chainstays are a feature of folding bikes, and as xenologer pointed out ^^ this can be a complication with wider cassettes. You may have to rely on optimal derailleur adjustment and lubrication to minimize the noise.
I have two Dahons and a Tern, but they all have internally-geared hubs, which side-steps this problem entirely!

11 speed chains do have thinner plates and that's how they make the overall outside width narrower while keeping the inner spacing the same as for 10 speed chains. I've heard recommendations to use a 11 speed chain for a 10 speed setup because the tolerances for 11 speed chains are tighter out of necessity. So, it's worth a try.

I'm currently running a 1x10 setup with a 10-speed chain on a Dahon Speed folding bike.
This setup is causing a lot of chain noise in top and (especially) bottom gear, I think, because of the very angled chain line in those gears causing the chain to slightly rub against the adjacent sprockets. I've tried cleaning and lubing the chain, and tweaking the RD adjustments, which gave some improvement, but it could be better.
Would swapping the chain out for slightly narrower 11-speed chain help much, if any?

You'll get just under 0,2 mm clearance on each side. Might be enough to make the difference - might not.
Are you sure the rubbing is what causes the noise? Could be just the chain angle - the more crossed it is, the more noise it makes. Thicker lube can help with it up to a point (with more dust and dirt "collection").

note how the derailleur is mounted to the bike... They get bent very easily on these folding bikes.
Have the der. checked for straightness to the frame.... a twisted/bent Der. mount will cause all sorts of chain/cassette noise.... changing chain width a few thousandths of an inch will not solve the issue.
once the derailleur is true to the frame, readjusting the cable will get things running correctly.
Avoid laying the bike down on the right side... ALWAYS lay it down on the left side... this will help you to not re-bend the derailleur mount. Crashes often bend the der. mounts, too....
