If your talking about 1 public static ip address no you cant
you would need the 2nd office to be on some sort of private wire or layer 2 trunk and it would need to break out the office 1 public ips
The public ip is unique on the internet it cant exist in two places or it will cause blackhole routing
If the 2 offices are close enough to run cables between them then you could but if you can only route out of 1 device with 1 public ip
