Sure, you can.
First you need to sign up for SkyparkCDN and create a CDN Resource. Login to your 1C-Bitrix, open the marketplace in your website administration panel. Go to Solutions Catalog and type SkyparkCDN in the search field. As soon as the plugin is found, click Instal. In the plugin settings specify a CDN-domain or a CNAME and list types of files that will be cached by CDN. Done!
