Yes, you'd need access to the TextMorph instance, and write something like:
button := SimpleButtonMorph newWithLabel: 'change text'.
button
	target: tm;
		actionSelector: #contents:;
		arguments: #('new text'); 
		openInWorld

If you didn't create the TextMorph and can't get access to it, you can find
it by searching through the world's submorphs (recursively if nec.)
