EDIT: We can use block technique. And put it where you want. For example, insert this block in your template:

{{block class='Company\\Module\\Block\\Email\\Logo' 
area='frontend' template='Company_Module::email/logo.phtml'}}

Your custom block:

<?php

namespace Company\Module\Block\Email;

use Magento\Framework\View\Element\Template;

class Logo extends \Magento\Framework\View\Element\Template
{
    protected $logo;

    public function __construct(
        Template\Context $context,
        \Magento\Theme\Block\Html\Header\Logo $logo,
        array $data = []
    )
    {
        $this->logo = $logo;
        parent::__construct($context, $data);
    }

    /**
     * Get logo image URL
     *
     * @return string
     */
    public function getLogoSrc()
    {
        return $this->logo->getLogoSrc();
    }

}

Template: view/templates/email/logo.phtml

<?php
/** @var $block \Company\Module\Block\Email\Logo */
/** @var $this  \Company\Module\Block\Email\Logo*/
?>

<img src="<?php echo $this->getLogoSrc()?>" alt="<?php echo __('Logo Image'); ?>"/>
