No. A chart created with User Impersonation will only have User Impersonation enabled for the specific Confluence page on which it was created. This is because of the unique hash that is associated with the chart is related to the Confluence page ID. Therefore, if the page ID changes because the chart is copied to a new page, then the unique hash will no longer match what is stored in the database and the chart will revert to the default setting of no impersonation and load the data as the current user.
This means that, if you copy the chart to a new page it will keep all the configuration (JQL, colors, title, etc.) but it will switch back to the default setting of no impersonation and load the data as the current user.
