If you don't mind a hacky workaround, you can accomplish this with the help of
an empty class:
node nodename1, nodename2, nodename3, nodename4 {
if $fqdn == "nodename2" {
$class2 = "class2"
} else {
$class2 = "null_class"
}
class { "class1": } ->
class { "$class2": } ->
class { "class3": } ->
class { "class4": }
}
class null_class { }
