Try with private properties, check on jsfiddle

var map = L.map('map').setView([51.505, -0.09], 13);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  attribution: '&copy; <a href="https://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

var markers = []

function createMarker(coords) {
  var id
  if (markers.length < 1) id = 0
  else id = markers[markers.length - 1]._id + 1
  var popupContent =
    '<p>Some Infomation</p></br>' +
    '<p>test</p></br>' +
    '<button onclick="clearMarker(' + id + ')">Clear Marker</button>';
  myMarker = L.marker(coords, {
    draggable: false
  });
  myMarker._id = id
  var myPopup = myMarker.bindPopup(popupContent, {
    closeButton: false
  });
  map.addLayer(myMarker)
  markers.push(myMarker)
}

function clearMarker(id) {
  console.log(markers)
  var new_markers = []
  markers.forEach(function(marker) {
    if (marker._id == id) map.removeLayer(marker)
    else new_markers.push(marker)
  })
  markers = new_markers
}
createMarker([51.5, -0.09])
createMarker([51.5, -0.093])
createMarker([51.5, -0.096])
