Not when I test it. I get:

E499: Empty file name for '%' or '#', only works with ":p:h"

for "VIM - Vi IMproved 7.3 (2010 Aug 15, compiled May 4 2012 04:25:35)".
Does it work differently in other versions?

You can change the behavior to put the line at the end of the buffer by
specifying a line number of zero to the read command:

:new | :0r !ruby filename

It's difficult to regain control of a ex mode : command after a ! in
order delete the extra line entirely, but I expect it can be done.
