In this case, no. I suspect the use of setq-default comes from a cut and 
paste of setting mode-line-format, which is a buffer-local variable, so 
setq-default is required to set a default value - setq overrides the 
value for the current buffer only.

The first element in the list is a symbol, which according to the doc 
string for mode-line-format (referenced from frame-title-format) causes 
the list to be treated as a conditional:
ie at runtime it acts like this:
(if invocation-name
   "@"
 system-name " - " ...)

To get what you expected, you need to make the first element of the list 
a string:

(setq frame-title-format
   '("" invocation-name "@" system-name " - " ...))
