I was able to do this when closing a UK Platinum account. All UK Amex MR points were transferred to my existing US MR account. Best thing of all is that they were not transferred on a 1:1 basis, but on a ratio based on the $:£ exchange rate at that time.
I was also told when signing up for my UK Platinum account that a transfer of UK MR points to US MR points could be done on a regular basis and was not just limited to accounts being closed. Given my experience with UK Platinum customer service, though, there's a fairly good chance that the person who told me this had no idea what they were talking about.
