No problem using a 12 volt instead of 10 volt as long as all other specs the same right? (1n4742a instead of 1n4740a)

It depends on the exact application. It could make a very big difference.
I wouldn't be substituting like that for zeners.
Ok, started getting a missing segment on master, display 1 and 2 and found toasty resistor and noticed the diode had been little hot but still ok. Local Radio shack has the 4742 but not the 40. I will just leave it.
Thanks
If you need a 1n4740a, Great Plains has it https://www.greatplainselectronics.com/products.asp?cat=158
