Sure.
Babel changes the meaning of some characters;
e.g. " ! ' ` ?
different ones are changed for different languages.

However, it provides a way to counter these changes.
Various versions of Babel have used different macro-names
for the switch to turn off these special features.

Just wrap the diagram with the default language:

{\english
    \xymatrix at M=0pt{
    A\ar[dr]!L&&A\ar[dl]\\
    &B\POS!R\ar[u]
    }
}
