No. I suppose \r would be shorter, but in vim when to use \r or \n is confusing.

:help expr-quote

one can use single-quotes, and type a ^M by pressing ctrl-V first, but for the purposes of a group post, confusion can result when various web browsers and mail clients mangle the non-printing character. Using "\<cr>" avoids that and also is plain to human readers what is intended. In fact no quotes are needed, and the execute is not needed, I just tried
:g//normal v//e^M$"Ay
where ^M appears I typed Control-V and pressed enter. Simpler, though, to give a command that readers can copy and paste.
