The Queen of England might not be as ruthless as her royal counterparts in Game of Thrones, but she still has to abide by a strict monarchist code. At least, that's what Game of Thrones show-runners David Benioff and D.B. Weiss explained to Seth Meyers on an episode of Late Night.
Last year, Queen Elizabeth and her entourage visited the Game of Thrones production in Northern Ireland and perused the various props and sets with her usual level of entitled disinterest/stoicism. Indeed, many fans were disappointed to discover the Queen did not take the opportunity to sit on the Iron Throne, which let's face it, would have resulted in countless meme images.
However, according to Denioff and Weiss, there's a very good reason for that. Benioff explained:
Apparently the Queen of England is not allowed to sit on a foreign throne. This is an esoteric rule we didn’t know about until that moment.

Apparently, this rule also extends to foreign fictional thrones, although another possible explanation could be that Queen Elizabeth has no idea what Game of Thrones actually is and literally thought it was a rather distasteful foreign throne.
Another more plausible explanation is that the Buckingham Palace authorities were not keen on putting the Queen into any position which compromises her aristocratic dignity and/or makes her seem remotely human or personable. They leave that stuff to Prince Harry.
Ultimately, it's probably a good thing the Queen didn't sit in the Iron Throne and stake a claim on the Seven Kingdoms. Queen Elizabeth hasn't burnt anyone alive for years, meaning the addition of the British royal family to Game of Thrones would hardly make it more exciting.
Game of Thrones Season 5 premieres on April 12 on HBO.
