Answer

No, it is not possible to change a field name in ArcGIS Online or Portal for ArcGIS. Once a field name is set and saved in its source layer, it cannot be changed. However, the display name of the field name can be changed in ArcGIS Online or Portal for ArcGIS. A display name is the field name displayed on the hosted feature layer's attribute table. Refer to ArcGIS Online: Set a display name or Portal for ArcGIS: Set a display name for more information and instructions to change a field's display name.
