Two theme options pages for a theme

is there a way of doing this?

Yes, just go and do it? There is no inherent or implied limit to creating admin pages.

Both would be using the same options would this casue a issue?

No, unless you code it in a way that it does. If both pages are going to be modifying same array of values (for example) they need to be careful not to blank or otherwise mangle each other’s items.
