the function you propose can actually be a mere macro:

#define gtk_tooltips_remove_tip (tip, widget) gtk_tooltips_set_tip (tip, widget, NULL, NULL)

i think we better provide something like
gtk_widget_remove_tip (GtkWidget *widget)
{
  GtkTooltipsData *tip_data;
  
  tip_data = gtk_tooltips_data_get (widget);
  if (tip_data)
    gtk_tooltips_set_tip (tip_data->tooltips, widget, NULL, NULL);
}
