Is it possible to align a button with a textbox using the Bootstrap 4 layout system?

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row justify-content-center mb-4">
<div class="col col-4">
<input type="text"/>
</div>
<div class="col col-4">
<input type="text"/>
</div>
</div>
<div class="row justify-content-center mb-4">
<div class="col">
<input type="button" class="btn" value="Go"/>
</div>
</div>
I am aware that I can place everything in the same row and align the button under the textbox, but this would require creating a new CSS class for adjusting spacing... I am seeking a cleaner solution utilizing the existing Bootstrap 4 classes.
