There is no difference, the same fonts are loaded, I tried this a month ago.

Now that I'm looking at it again at

This has resulted in derivatives of Bitstream Charter becoming available, including Charis SIL.
What about adding
     http://scripts.sil.org/CharisSILfont
to the distribution, possibly including TeX Live, and replacing the
definitions to use CharisSIL in XeTeX/LuaTeX instead of Bitstream
Charter? The same move that has happened with TeX Gyre? Any comments?
Suggestions?
The fonts include more characters but come without any kerning information.
The kerning of Bitstream Charter is so dodgy that this is not
a big loss.
I have no problem if this is so.

I encountered another problem in my own typescripts for Charis SIL,
I could use the bold style when I use the file name but not for the font name.

Try this:

\starttypescript [serif] [charissil]
  \setups[font:fallback:serif]
  \definefontsynonym [Serif]           [CharisSIL-Regular]
  \definefontsynonym [SerifItalic]     [CharisSIL-Italic]
  \definefontsynonym [SerifBold]       [CharisSIL-Bold]
  \definefontsynonym [SerifBoldItalic] [CharisSIL-BoldItalic]
\stoptypescript

\starttypescript [serif] [charissil]
  \definefontsynonym [CharisSIL-Regular]    [file:CharisSILR]
[features=default]
  \definefontsynonym [CharisSIL-Italic]     [file:CharisSILI]
[features=default]
  \definefontsynonym [CharisSIL-Bold]       [file:CharisSILB]
[features=default]
  \definefontsynonym [CharisSIL-BoldItalic] [file:CharisSILBI]
[features=default]
\stoptypescript

\starttypescript [charissil]
  \definetypeface [charissil] [rm] [serif] [charissil] [default]
\stoptypescript

\usetypescript[charissil]
\setupbodyfont[charissil]

\starttext

\tf Text

\it Text

\bf Text

\bi Text

\stoptext

I get all four style in the output but when I use the font name in the
definition
the normal bold style is replace by the bolditalic style.

\starttypescript [serif] [charissil]
  \definefontsynonym [CharisSIL-Regular]    [name:Charis SIL]
   [features=default]
  \definefontsynonym [CharisSIL-Italic]     [name:Charis SIL Italic]
   [features=default]
  \definefontsynonym [CharisSIL-Bold]       [name:Charis SIL Bold]
   [features=default]
  \definefontsynonym [CharisSIL-BoldItalic] [name:Charis SIL Bold
Italic] [features=default]
\stoptypescript
