The && short-circuits, so the second part of the conditional only
gets evaluated if the first part is true.
I know I can use isset, it just adds a bunch of extra code. I like to find minimal solutions to these things if possible as they are easier to read, and faster to execute.

As already suggested, isset() and empty() are good choices here. Which one you choose it dependent on what exactly your truth table is. Or, it might work better for you to use !isset() or even !empty().
if (!empty($_POST['checkboxfieldname']) {
/** do stuff */
