I was thinking about changing from 40T to 42T, the rear is 11-50.
Can I do this without changing the chain or will the length be tight?

Probably yeah.
That should work out. If you’re worried, consult a chain length calculator.
The question is why you’d want to do it though, a 2t difference in the chainring won’t be particularly noticeable. For the difference in speed, you can consult a gear ratio calculator.
Just try it and find out. If you need two more links, then just add them using a quick link.
If you don’t have the extra links already, just take them off a new chain and then save that chain for next time.
I reckon it would be fine. We measure chains small/small 95% of the time and it looks like the derailleur isnt fully maxed out. I’d test it in the stand first
It should be fine, worst case a new chain, or maybe add a couple extra split-links (ssshhj I didn’t say that and have never done that myself).
