Indeed. More easily because the US/UK extradition agreement only requires each country's courts to apply the same tests as they use domestically to allow an arrest. In the US that test is called probable cause, in the UK it's called reasonable suspicion.

(Some people at the time felt that this was not fair as the US test is arguably a tougher one but arguably that just reflects the country's domestic arrest policies being different. In any case, the UK refuses far more US extradition requests than vice versa. If you want to read 400 pages on this, the Baker Extradition review which also covers the European Arrest Warrant and the Prima Facie test is available online.)
