If you're refering to the screen(1) UNIX program, then yes, it can do
that (at least the more recent versions can ... not sure about older

Check your man page for screen(1) for something similar to:

In fact, since you seem to be having trouble having the EXTERNAL facility
in "lynx" firing-up "w3m", have a go at letting "screen" start it up
(with lynx's EXTERNAL doing something like "screen w3m %s"), and see if
that works.
