Not really. i mean, it is not as hard-coded as some role ( second striker ) for example, but he is still coded in term of width. which means that, this role will whatever using the width to a more extent than an other role in midfield no matter what mentality u use ( to some extent). To me, CM(s) even with the TI instruction to "stay wider" will tend to do use more width positionning, yes, but it wont be the same. ( for example, during defensive phases). Plus, CM will tend to use width depending on your current mentality whereas the carrilero will do that anyway. that's a big difference.
