That depends on whether you modified the syntax class of '_' in 4.01.
The standard code in 4.01 uses word syntax for '_' while defining a case
exception, which would select BSB_LED_Init.
But if you changed the syntax class for '_' in
ada-mode-symbol-syntax-table to symbol, then it would select LED.
In 5.01, I don't mess with the syntax tables as much; there is only one,
and _ has symbol, not word, syntax.
(Except that I always change that to make _ have word syntax, so moving
by word jumps entire identifiers. Which makes testing this stuff
confusing :).
ada-case-create-exception explicitly includes both w and _ syntax, so _
is always included in the default word.

4.01 supported the active region, yes. That's the way I always use it,
since I always change _ to have word syntax.
It is simple to drop _ from the search syntax when defining a partial
case exception, which gives the behavior you describe:
ada-mode.el:1024
(unless word
(if (use-region-p)
(setq word (buffer-substring-no-properties (region-beginning)
(region-end)))
(save-excursion
(let ((syntax (if partial "w" "w_")))
(skip-syntax-backward syntax)
(setq word
(buffer-substring-no-properties
(point)
(progn (skip-syntax-forward syntax) (point))
))))))
