You could use it safely. For example 

ugettext_lazy('{foo}').format(foo='bar')

The translation program xgettext, which is used by Django, does not care about the content to be translated. It just searches .py file for keywords such as ugettext_lazy or _ to collect the translatable strings(refs the manual of xgettext and Django code)

Furthermore, the .format() method above is a wrapper provided by the proxy object, like:

>>> ugettext_lazy(u'{foo}').format
<bound method __proxy__.__wrapper__ of <django.utils.functional.__proxy__ object at 0x102f19050>>

The invoking of the above .format() would get u'{foo}' to be translated to some unicode value, then call value.format with actual arguments. You could see that the translation and value.format happen in different stages.
