There should not be any real problem to link wikimedia.org.uk directly to Wikimedia UK chapter wiki (wherever it's hosted).
It depends on how the WMF has everything set up. They have a complicated setup for hosting multiple wikis, it may well be hard-coded that they all use the WMF domains. I'm cross-posting this to wikitech-l, hopefully someone there can clarify the situation. Can a wiki hosted on the WMF servers use a non-WMF domain?
