Yes, and the standout is Dulux Stormy Retreat (LRV 13.3). At ΔE 1.7 from Kendall Charcoal that's a very close match — close enough that you'd struggle to tell them apart on a wall once dry, and certainly nobody walking into the room ever will. Given Dulux trade prices sit well below Benjamin Moore's, that's a proper saving with no real compromise on colour.
Kendall Charcoal is that lovely deep warm grey-green that reads almost black in low light and softens to a smoky charcoal when the sun hits it. The reason Stormy Retreat works so well is it carries the same warmth — a lot of "charcoal" greys go cold and bluish, which kills the whole effect. Stormy Retreat doesn't.
The other two contenders are further off. Crown Smokey Grey (LRV 11.3) comes in at ΔE 4.3, and COAT The Coal Drop (LRV 14) at ΔE 4.1. Both are perfectly nice charcoals in their own right, but at those numbers they're noticeably different colours rather than dupes — you'd see the shift if you put them next to the original. If you genuinely want Kendall Charcoal on a budget, go Stormy Retreat.
The "but what about" here: don't assume a cheaper paint means a worse finish. Dulux's trade emulsions cover and lay off beautifully, and for a deep colour like this you'll want a good opacity anyway. On a dark shade, always tint your primer or use a grey undercoat — going straight over white means three or four coats and a patchy result. A mid-grey base gets you there in two.
One caveat: deep colours can vary slightly batch to batch and brand to brand once you account for sheen. If this is a feature wall or a small room where you'll really study it, order a sample pot of Stormy Retreat and live with it for a day or two before committing. But on the numbers, it's a cracking swap.
