Theoretically, you can activate a COD payment method and then simply hide this step with basic CSS and a bit of JS to open the final step in the default checkout.
But Opencart heavily relies on Payment_address. Payment Address has several fields that are required like country, zone and often postcode.
Removing the payment_address will break the whole system. What you can do is via simple HTML and CSS, populate the fields with default values and then hide with CSS.
for example in catalog/view/theme/default/template/checkout/payment_address.twig
...html
<div class="form-group required">
<label class="col-sm-2 control-label" for="input-payment-firstname">{{ entry_firstname }}</label>
<div class="col-sm-10">
<input type="text" name="firstname" value="<MY_DEFAULT_FIRST_NAME>" placeholder="{{ entry_firstname }}" id="input-payment-firstname" class="form-control" />
</div>
</div>
...
do this for all the fields.
then in catalog/view/theme/default/template/checkout/checkout.twig do style="display:none'
<div class="panel panel-default" style="display:none">
<div class="panel-heading">
<h4 class="panel-title">{{ text_checkout_account }}</h4>
</div>
<div class="panel-collapse collapse" id="collapse-payment-address">
<div class="panel-body"></div>
</div>
</div>
{% else %}
<div class="panel panel-default" style="display:none">
<div class="panel-heading">
<h4 class="panel-title">{{ text_checkout_payment_address }}</h4>
</div>
<div class="panel-collapse collapse" id="collapse-payment-address">
<div class="panel-body"></div>
</div>
</div>
this will just hide the payment_address block but it will still be there.
and now you need to skip the payment address step by calling the Continue button via JavaScript
so in the same file catalog/view/theme/default/template/checkout/checkout.twig
after line 165
$('a[href=\'#collapse-payment-address\']').trigger('click');
//add this code to trigger continue button:
$('#button-payment-address').trigger('click');
You might need to wrap the trigger click action with setTimeout becuase you might trigger the click before the form is actually loaded.
I would also advise to do this in a CUSTOM theme folder, and not in the default opencart theme. this way you can do the modifications without touching the core file.
