Morphology
The verb 'loosen' (make less tight) combined with 'tongue' (here metonymically 'speech') yields a directly inferable meaning: to make someone's speech less restrained. This metaphorical use of 'tongue' for speaking is common cross-linguistically, so a B1 learner who knows the constituents would very likely guess the MWE's meaning.
Etymology
The idiom loosen someone's tongue may come from the idea of a tied or tight tongue that cannot move; when you loosen it, the person can speak more easily. So, it means 'to make someone willing to talk' or 'to reveal secrets'.
