No you cannot do that:
the field names are keys in a Python dictionary, in what you write the second
invoice_linewill overwrite the first onethis would mess up OpenERP’s ORM anyway as it does not handle relations to different tables.
So you need two different columns, one relative to
account.invoice.lineand the other toaccount.service.line. If you really need a merged view, then you can add a function field which will return the union of the invoice and service lines found by the two previous fields. But I’m not sure the forms will be able to handle this.
