Sure, just duplicate the business template in a child theme, and then you can rename this to whatever you wish and apply your own unique CSS styles to the new elements you define in the new template.
If this is all above your head, you may consider having some help to get it done. Otherwise, start with making a child theme, then go into the parent theme and copy the business template file and rename it to something else, along with changing the header name so that it registers properly in the page options as an available template. Then create your new page using your new template. Create the custom css you need and add it to the child theme’s style.css or use the simple custom css plugin.
