Chain length question

Toying with the idea of switching to a 1x10 set up which will mean changing chainrings and cassette.

I'm currently running a 38t outer chainring and 32t largest sprocket. If I switch to a 34t chainring and 36t largest sprocket, will I get away with using the same chain? I'm taking 4 teeth off the chainring and adding 4 teeth to the sprocket which, in my mind, cancels each other out.

Is it that simple, or am I missing something?

    I'd be getting a new chain too and then just measure and cut it to length

    yeah, that's the safest bet but I'm trying to do it on the cheap. Would be an excuse to see what a gold chain looks like on it, though.

    Assuming the chain length is right now, it will still be right.
