A simple solution would be passing multiple city names as an array instead of single city name to the openCity function.

In the following example, the content of 2 tabs with the id London and Paris will show up when you click on the tab London.

function openCity(evt, cityNames) {
    let i, x, tablinks;
    
    x = document.getElementsByClassName("city");
    for (i = 0; i < x.length; i++) {
        x[i].style.display = "none";
    }
    
    tablinks = document.getElementsByClassName("tablink");
    for (i = 0; i < x.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" w3-border-red", "");
    }
  
    cityNames.map(function(city) {
        document.getElementById(city).style.display = "block";
    });
    
    evt.currentTarget.firstElementChild.className += " w3-border-red";
}
