Can any two devices (part of different network/locations
Absolutely! That is precisely what RFC 1918 private addressing is for. The problem comes when those two devices want to talk to one another. In that case, they need to connect via a trusted third party that has a global address, either as a direct IANA IPv4 Address Space Registry Dec 27, 2019 IPv4 address exhaustion - Wikipedia

This document describes address allocation for private internets. The allocation permits full network layer connectivity among all hosts inside an enterprise as well as among all public hosts of different enterprises. The cost of using private internet address space is the potentially costly effort to renumber hosts and networks between public IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses.Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s, when the Internet started experiencing dramatic growth. This depletion is one of the reasons for the development and deployment of its successor protocol, IPv6. RFC 1918 : Address Allocation for Private Internets St´ephane Bortzmeyer
