yes you can.
1) Do not use the Logo feature. Leave it empty (if you already added one, click Restore)
2) in SEO > header Title or Header Description (according to where you want the logo to appear), insert the html calling the logo. E.g.
<img src="http://www.SOMEWEBSITE.com/images/en/_12d_header.png" alt="my apartments logo" name="logo" width="378" height="104" border="0" />
and insert a different link to each image for each languge (click on the flags icon to see all languages).
I suggest to upload the various logos in your Image Manager (go to any Dynamic page and look for the image icon until you find how to upload) and call the link to them.
This is better for SEO that placing the images in another website.
