This comment implies yes:
/*
* Lookup ``tn'' in each possible terminfo file until
* we find it or reach the end.
*/
for (fname = pathvec; *fname; fname++) {
And this one from read_entry.c:
#ifdef __OpenBSD__
/* First check the BSD terminfo.db file */
if (_nc_read_bsd_terminfo_entry(name, filename, tp) == 1)
return (1);
#endif /* __OpenBSD__ */
.
