You can do it, but as it is very bad style I don't tell you.

imagine:
your extension extends the record with this field and you use it in your 
intention.
another extension is developed parallel and inserts also a field with the 
name 'target', but uses it in a very own usage (and may have another 
fieldtype).

and then there is a user who wants both extension installed.
no one can tell which type the field has to be. no one can tell which 
value leads to which behavior.

The solution in TYPO3: every extension generates fields with unique 
fieldnames by using the extension key as prefix.

the same with tablenames.
