Short answer: yes, with a 'but.' Long answer: no, with an 'if.' What kind of beer are you making? There's not a big difference, but there is difference. Yes, you can use it but it won't taste exactly the same. If you're not trying to brew a clone of a British beer, it'll be fine. It's kinda like the difference between pils and 2-row. In a stout it doesn't matter. In a pilsner it matters a lot.
