If you suspect it is something actually in the glass (not something that can be wiped away), than a replacement might be the better idea. If it's something in the glass, that element (or several) might need to be exchanged and who knows how the performance/centering will be afterwards. Once it has been to service, replacing the whole lens might no longer be a valid option...
I haven't heard of significant sample variation regarding the 70-200 VR II. However, whatever lens and whatever brand, you'll have to check any individual lens anyway. Even if the risk to get a lemon is low, it's still a risk...
