Here's how the release cadence works:
First, you can opt into the bleeding-edge update stream http://i.imgur.com/7gWXLd3.png
Next is "current branch" for normal consumers, who are forcibly kept up to date (arguably a good thing, since they don't have an IT department to update their computers for them) http://i.imgur.com/kYkvffQ.png
Third is "current branch for business". Businesses are still required to upgrade, but they get a bit more time to ensure rollouts go smoothly. CBB can delay updates but not indefinitely. http://i.imgur.com/vsejEFC.png
Lastly, Enterprise and Education SKUs have access to the "long term servicing branch" where you can indefinitely delay updates, and/or run your own WSUS update servers. http://i.imgur.com/2JsFq1Y.png
tl;dr yes, but you need to pay for the Enterprise SKU for that privilege.
