Unfortunately not. OpenType fonts look like TrueType fonts from the
outside, but the actual glyph data can be stored in two different
formats. One can either use classical TrueType glyph data (quadratic
curves) or so called CFF glyph data (cubic curves). The latter is very
similar to PostScript Type1 glyph data. In addition, OpenType fonts can
contain other information like GSUB or GPOS tables that are not present
in normal TrueType fonts.
Every application that can use TrueType fonts can use OpenType fonts
with TruType outlines (sans the additional information). That's why
'.ttf' is used for such fonts. The ending '.otf' normally refers to an
OpenType fonts with CFF outlines. There aren't many F/OS applications
that support those (dvipdfmx and scribus come to mind, pdftex has a
/very/ limited support).
