Yes. The Constitution has no limitation to serving as Vice President... only President. That limitation is two elected terms or 10 years. As a recent example, Vice President Bush served for two full terms under Reagan before running and winning the Presidency. He also ran for a second term against Clinton but lost. VP Gore served two terms and ran after that for Presidency and won (but still lost)... but thats another story.

The real question you should be asking,however, is whether a President who has served two terms or 10 years can then serve as Vice President. The Answer to that is NO although that has never been tested. The 12th Amendment states"no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States."
