I am looking to find out if anyone can firmly tell me if CUCM version 8.6.2 is capable of using a Cisco 4451 ISR for voice gateways? I cannot find a drop down in the gateways sub application that allows 44XX routers.

Notice that only applies to a some of the ISR 4Ks and not all of them. If they're not listed, your only options would be to use them as H.323 or upgrade to 10.5(2)

As Jaime has mentioned (+5) You can use H323 or SIP as well with 8.6. As I have highlighted in the notes when using H323/SIP - CUCM needs no knowledge of the platform.
Ref here to data sheet for ISR routers:

See below screenshots for SIP:
Using H323:
Using MGCP; you will need to be on bare minimum of 9.1(2)
