Can I use a translated Page as an Interlanguage link?
For example, if I have the page wiki.com/Page1/
and the translated page is wiki.com/Page1/es
Can I use it in the interlaguage link list (bottom left, "In other languages")

Yes, you can set interwikis to other languages that point to the same wiki.
You can try using http://examplewiki.com/wiki/$1/es as the URL to use only [[es:Page1]] instead of [[es:Page1/es]], if all your translated pages are going to have the /es suffix.
