I'm sure you've tried it and discovered the answer is "no".  The
backslash will append the next line to the previous line and it won't
be considered a make statement.

You need to put the ifdef outside the recipe:

    ifeq (...)
      BAR = | bar
    else
      BAR =
    endif

    target:
            foo $(BAR) | baz
