This is not straight possible, because the CompanyLogoEnable can only be set for custom reports, where the headertype is set to header3. The report headers other fields are different too.
Of course it is possible to use this in the standard headertype 'header1' as well. You will have to change the /reporting/includes/pdf_report.inc file in the header1 memberfunction. You can look in header3 memberfunction how this is handled.
