Solved it myself. You can not use the if inside the if shortcode but you can do &.
[if value1="{order_meta key='additional_field_681'}" operator="equal" value2="Nee" & if value1="{order_meta key='additional_field_644'}" operator="equal" value2="Locatie_Amstelveen"]
So it checks of both conditions are applied at the same time
