Ok, I have a cable between two cisco switches. The port on switch A is configured as switchport access vlan 2 and the port on switch B is configured as switchport access vlan 3. For the sake of the current question let's say I cannot change the number of these access vlans. Also, because these are access ports, traffic should be untagged and a trunk is not formed. Traffic is successfully transferred between switches.

However, I am getting a "Native Vlan Mismatch" error.

Aren't these mismatches generally shown only when a trunk is formed?

Will the same problems associated with trunks and a native vlan mismatch occur?

CDP (LLDP) lists how the each port is configured. Cisco, in their infinite wisdom, thinks access ports in different VLANs are an error. They aren't, but it could be a misconfiguration. Disable CDP and the switch will shut up about it.
