While it isn't possible to pass a namespace in a variable to use, you can place the namespace and the expected "short" class name in a variable and use that in most places where you'd need it, like invoking new.

$namespace = '\foo\bar';
$class = 'baz';
$fully_qualified = $namespace . '\\'. $class; // \foo\bar\baz
$a_foo_bar_baz = new $fully_qualified(...);
var_dump( $a_foo_bar_baz instanceof $fully_qualified ); // true
