If I've lost track of a filename that a channel was opened for, is

In other words, after doing the following:

set file_handle [open $filename r]

can I then use $file_handle to determine $filename?

If you're at the design step, just keep the association at script
level.
If you want to debug a large and barely modifiable script, on Linux
you can do some I/O on the channel under strace, find the underlying
file descriptor, and then look for the same descriptor in /proc/[pid]/
fd. These are pseudo-symbolic links giving the path of the files (or
pipe or socket IDs).
