Yes. Most people's CV's who have been around for a while are too long anyway. The goal should be one page, with only the most recent/relevant experience.

Empirically, I'm getting about the same results from my 1 page and my 2 page CV, based on call back rates, funnel progression, and interviewer comments. Go ahead and use two pages if the incremental content is relevant to your overall pitch.

(In my case the extra material is relevant... I've run pricing at five companies, which is usually a massively cross-functional job. Unlike my typical competitor, I've also mastered most of the supporting technical, accounting, and commercial disciplines... which makes me a one stop shop for serious pricing problems.)

Don't get me wrong, two pages might be optimal if you have lots of varied experience. I wasn't trying to make a case for one page only. It really depends on what you want to convey to interviewers.
